## About the Demarcus D. Smith Scholarship

Mr. Demarcus D. and Mrs. Fran Smith have established a Mathematics Scholarship Fund to support full-time undergraduate students in the Department of Mathematics at LSU. The scholarship supports the careers of outstanding students whose efforts embrace both mathematics research and mathematics education.

Guided by mathematics faculty, scholarship recipients engage in inquiries and investigations that make creative contributions to mathematics and/or the teaching of mathematics. They identify and describe an original, math-intensive disciplinary or interdisciplinary research question and articulate research findings through papers, posters, and oral presentations. With the Demarcus D. Smith III Scholarships, these students gain multi-semester extracurricular experience in

### Aaron Cao

#### Brief biography

I grew up in Lafayette, Louisiana and first became interested in mathematics through competitions such as the AMC. I'm a senior majoring in Mathematics (Actuarial Concentration) and one of the instructors of the LSU Math Circle. My main research area is financial mathematics, which I hope to pursue further in graduate school. My other hobbies include watching anime and playing Magic: The Gathering. I hope to help develop mathematical outreach programs in Louisiana and later work in financial data science.

#### Mathematical and Educational Activities

For the majority of my undergraduate career, I've been concerned with developing an intuitive and comprehensive mathematics enrichment curriculum for gifted high school students. My current avenue for deploying my curriculum is competition mathematics. In many ways, I believe that competition mathematics gives unique opportunities for Louisiana high schoolers to shine. By contributing content to programs such as the LSU Math Circle, we can begin to enhance the mathematics background of students in the Baton Rouge area and hopefully expand to the entire state.

My background in mathematics education began when I was a middle and high school student partaking in the MAA series of competitions beginning with the American Mathematics Competition. Through summer programs such as AwesomeMath and the Ross Mathematics Program, I became exposed to the high school competition mathematics community. It was easy to realize that the majority of students in Louisiana, even mathematics enthusiasts, did not have access to the resources that a competition community can provide, so upon graduating high school I spent several summers working as a teaching assistant at AwesomeMath.

During my early undergraduate years at LSU, I was also introduced to the LSU Math Circle. Though I would not extensively participate with Math Circle until my later undergraduate years, I immediately saw an opportunity to share my knowledge and experience with the growing Baton Rouge math competition community. In high school, I was able to qualify for the USA Mathematics Olympiad, and I have a reasonable grasp of the topics the students would need to know. During Steven Olsen's tenure as Math Circle coordinator, I began gradually transitioning the previous, more laidback, Math Circle curriculum to a more rigorous form.

Through hours upon hours of work in collaboration with the current coordinator Brooke Mendoza, I was able to write expansive mathematics curricula in the four main competition topics: Algebra, Combinatorics, Number Theory, and Geometry. I believe that the Math Circle program under our leadership is has become competitive with some of the best math prep programs in the nation. I believe that establishing this sort of intellectual base for high schoolers will lay the groundwork for Louisiana students to truly shine in the years to come.

My work with the LSU Math Circle is perhaps the proudest achievement of my time as an undergraduate, but I am also looking forward to my career prospects after graduation. As an actuarial student, I have undertaken a bibliometrics research project under Dr. Lawrence Smolinsky. I have also passed the preliminary Probability Exam in the actuarial track and plan on taking the second Financial Mathematics exam in the winter. I am most interested in careers utilizing statistics and data science, and I'm currently in the interview process with several companies for potential data analytics positions after graduation.

### Dylan Spedale

I am a freshman majoring in mathematics, and I am hoping to include a secondary major under physics or computer science. I have a strong interest in mathematics, but I have not delved long and deep enough into its numerous areas to choose a particular field. But based on my experience with competition mathematics, my interests lie in discrete mathematics, particularly combinatorics. I am pursuing a mathematics concentration with aspirations to pursue research. Pure mathematics has a special place in my heart, and I hold it — as well as its practitioners — in very high respect due to its existence and development being for its own sake. I aspire to one day develop my own original mathematical ideas as I see this as the utmost expression of creativity and passion. My second greatest interest behind mathematics is weightlifting. I currently do this causally, but I hope to join the LSU powerlifting team in the future and compete in events.

#### Brief biography

As of now, my mathematical endeavors involve developing the foundations in various areas of mathematics that I will need for future learning, including number theory, real analysis, and abstract algebra. I strive to improve my mathematical knowledge through self-studying and hope to develop strong bases of knowledge from which I may approach more advanced topics in the future. I have interests in mathematical research, and I hope to pursue it further and in more detail in my coming years. Most of all, my greatest desire is to reach a point of sophistication wherein I may converse with professors and other professionals about mathematical topics, including research topics. Belonging to the community is a great desire of mine.

#### Mathematical and Educational Activities

While I have never sought any official teaching positions, I have greatly enjoyed the times that I had to try to teach someone something new. I particularly enjoy teaching someone a topic that I previously struggled with, as it invokes in me a feeling of compassion and service to the student. It is especially exciting if the insight that explained the topic “at a glance” for myself resonates in the same way with the student. Furthermore, teaching topics have been an invaluable tool for helping me check my understanding of a topic and identifying any implicit assumptions I may have in my knowledge. I do not plan to pursue a teaching career as of now, but I do plan to tutor students in my coming years at university.

#### Brief biography

I am a sophomore seeking a dual degree in Computer Science and Mathematics, with a minor is Business Administration. I am a huge outdoorsman and thoroughly enjoy rock climbing, bouldering and top-roping. Here at LSU, I was a member of ASME prior to engaging in pure Mathematics and its relation with Computer Science. The switch from mechanical engineering to this dual degree was chosen specifically to satisfy a thirst for WHY things are and WHERE they are going. I feel that Mathematics is the why and Computer Science is the where. The future is a combination of what we learn from the past and present. Prior to my college career at LSU, I attended Mandeville High School and was a 4-year varsity member of the Tennis Team, 3-year All-State Honor Band Participant for the Clarinet, and a member of Mu Alpha Theta.

#### Mathematical Activities

I am working on a research project with Professor Stephen Shipman involving spectral theory of quantum graphs. It beautifully incorporates complex variables, differential equations, linear algebra, algebraic geometry, and graph theory. This research opportunity for me is still in the infant stages, and I feel that I will gain an immeasurable amount of knowledge in fields I have not studied yet and a more solid feeling of knowledge in fields I have already studied.

#### Educational Activities

After being immersed with mathematics in my full Spring 2017 semester, I was driven to be able to share my knowledge and engage in educational activities here at LSU. Therefore, I worked as a tutor at the LSU Math Lab in Middleton Library. There, I helped tutor College Algebra and College Trigonometry to my peers. The experience has been undoubtedly beneficial in my mathematical growth. Knowing a subject is invaluable, but being able to explain more or less difficult material in a way that relates to your fellow peers truly makes you aware of previously learned material. This opportunity has provided me with remarkable teaching experience, IT incorporation with education, and a way to deepen my knowledge as I progress into mathematics.

Currently, I am working on a number theory research project under Dr. Robert Perlis that involves pairs of conjugate permutations.

### Avery St. Dizier

#### Brief biography

Avery St. Dizier is an undergraduate mathematics student at LSU. His interests lie in pure mathematics, particularly in Probability Theory and Combinatorics. Avery has worked at the University of Nebraska - Lincoln studying discrete calculus under Dr. Allan Peterson and at Cornell University studying Jacobian groups of regular matroids under Dr. Farbod Shokrieh. At LSU, he has done work on the matrix exponential and the Laplace transform under Dr. Frank Neubrander. He currently works as a tutor for Dr. Neubrander’s calculus classes, and also as a private tutor. He has taken multiple graduate level mathematics courses as an undergraduate and has presented at several research conferences at LSU and elsewhere.

#### Mathematical and Educational Activities

My long-term goal is to become a research mathematician and to spend my life creating new mathematics and inspiring the next generation of students to embrace mathematics. In the course of discovering my own research interests, I transitioned from computational work, implementing mathematical algorithms, to more pure work, including matroid theory and combinatorics. My diverse research experiences have broadened my mathematical toolkit while focusing my interests.

In my first semester at Louisiana State University (LSU), I dove into research with Dr. Frank Neubrander. When I started college, I only knew basic calculus. However, Dr. Neubrander relentlessly pushed my peers and me each week, opening our minds to the vibrant world of higher math. After a couple of months of weekly, late-night lectures, he introduced us to our research topic. Motivated by sharp error estimates for approximating strongly continuous operator semigroups using higher order Pade Approximations, he tasked us with implementing and testing new algorithms for approximating the matrix exponential using Mathematica and Matlab. We then carried the computation of the matrix exponential into the numerical inversion of the Laplace Transform. Despite what was suggested by the sharp error bounds, we discovered that the scaling and squaring used by the mainstream algorithms remained more computationally efficient than higher order approximations. I was then tasked with summarizing the algorithms and results in a technical report. We continued on to produce a poster which we presented at the Louisiana State University Undergraduate Research Conference. Dr. Neubrander showed me how research is actually done, not by following a predetermined path from the problem to the solution, but by slowly breaking down a seemingly impenetrable question into manageable pieces that can yield insight into the bigger mathematical picture.

After a year of working with Dr. Neubrander, I attended the Summer Research Program in applied mathematics at the University of Nebraska-Lincoln (UNL). I was mentored by Dr. Allan Peterson in the area of discrete calculus. Working with a larger group of students, I applied the knowledge of the Laplace Transform and the research philosophy that I had gained working with Dr. Neubrander to develop an analogue of the Laplace Transform in a radically different setting. We considered a set called the scaled number line, consisting of the orbit of a fixed based point under an affine map and its inverse. On this set, we first examined the expected analogues of the elementary functions and verified that they possessed properties similar to those of their continuous counterparts. Then, we focused on the discrete integral and the basic theory of difference equations. Guided by our intuitions from calculus, we formulated a definition for the discrete Laplace Transform, derived its properties, proved convergence and injectivity results, and demonstrated its effectiveness in solving discrete difference equations on the scaled number line. We collected our results into a paper that we submitted to the Pan-American Mathematical Journal. I also presented a poster on the research at the LSU Discover Research Conference and again at the 2014 Joint Mathematics Meeting. My research at UNL was my first experience contributing to mathematical theory. I greatly enjoyed the project, and it drew me to studying more abstract subjects when I returned to LSU. As I worked throughout the next semester to complete and submit the paper, I also began delving into my newfound interests by taking the first-year graduate courses in algebra, complex analysis, and topology.

Once I had completed a year of graduate-level coursework, I was able to pursue the new interests in pure mathematics that I had been exploring since the previous summer by attending Cornell University's REU program. I worked with another undergraduate, Esco He (Cornell University), and was mentored by Professor Farbod Shokrieh in the area of chip-firing games on graphs. Given a finite, connected graph with no loops, a chip-firing game is played by first assigning integer values, called “chips,” to each vertex. The objective of the game is to get each vertex out of “debt,” that is to make each vertex have a nonnegative value through a sequence of moves, where a move consists of allowing a vertex to fire by sending one chip to each adjacent vertex. The analysis of this game motivates the study of the Jacobian group, a quotient of the group of initial chip configurations under addition.

One interesting property of the Jacobian group is that the order of the group is exactly the number of spanning trees of the graph. There are many different, known explicit bijections between the set of spanning trees and the Jacobian group. However, all known bijections depend heavily on the graph-theoretic notion of vertices. Our goal was to construct a combinatorial bijection that could be extended to regular matroids, structures that capture the dependence relations between the columns of real matrices in which all subdeterminants are 0, 1, or -1. We began by studying an equivalent definition of the Jacobian compatible with regular matroids. Then, we analyzed a geometric construction that encoded the set of spanning trees as a tiling of space by higher-dimensional parallelepipeds and encoded Jacobian elements as corners of the parallelepipeds modulo an equivalence relation derived from the cycles in the matroid. After repeatedly varying the parameters and working out dozens of low-dimensional examples, I established a method for recreating the geometric bijection using only the combinatorics of the underlying matroid with no reference to the geometry. I then proved the equivalence of the geometric and combinatorial methods, establishing that the combinatorial method was indeed a bijection. However, unlike the geometric bijection, which has a natural inverse, the combinatorial bijection is difficult to invert. The project is ongoing, and we are in the process of drafting a paper with our results.

Since last summer, I have been focusing on probability theory. During the Cornell REU, I attended several fascinating seminars, including talks on mixing times of stochastic processes and connectivity of randomly growing networks. I have taken graduate courses in probability theory and real analysis in previous semesters, and I am currently taking stochastic analysis to prepare to undertake graduate studies in probability theory. I have applied to a number of graduate schools with strong programs and active research in probability theory, and I am eagerly awaiting replies.

### Jessica Wojtkiewicz

#### Brief biography

Jessica Wojtkiewicz is an undergraduate student pursuing a degree in Computational Mathematics at Louisiana State University. After taking Discrete Dynamical Systems with Dr. Peter Wolenski, Jessica was given the opportunity to work with the Math Consultation Clinic and an engineering firm in order to develop a Graphical User Interface in MATLAB to track a microwave transceiver on a hand-held device using eight optical-flow sensors. After this opportunity, Jessica learned that her mathematical interests could be found in real-life applications. Along with working on mathematical problems, Jessica is also a Resident Assistant for the Global Connections Residential College on LSU's campus. Jessica spends a lot of her time mentoring first-year students and is known to tutor a few of them in mathematics. In the future, Jessica plans to attend a graduate school to obtain a doctorate degree in Computational/Applied Mathematics.

#### Mathematical and Educational Activities

Mathematics has been a passion of mine since I was a young girl, but I never truly realized how much I loved mathematics until I had a couple of wonderful mathematics teachers throughout middle and high school. These teachers were able to show me how fascinating numbers were while teaching me how to apply this fascination with numbers to a multitude of real-life applications. It was this passion that these teachers instilled in me that led me to set a goal to pursue mathematics in college.

Currently, I am working towards acquiring a Bachelor of Science degree in Mathematics with a concentration in Computational Mathematics. My goal beyond graduation is to pursue a PhD in Computational/Applied Mathematics to create mathematical models and algorithms for industries or government labs. To help prepare myself for the rigor of graduate level research and to open up future possibilities in mathematics, I have participated in the Math Consultation Clinic at Louisiana State University with Dr. Peter Wolenski, Dr. Stephen Shipman, and Dr. Ameziane Harhad, as well as three graduate students and three undergraduate students pursuing degrees in mathematics. With this opportunity, I was able to create a Graphical User Interface in MATLAB that incorporated an algorithm that we developed in order to track a microwave transceiver on a hand-held device using eight optical-flow sensors. Exposure to this type of research will be advantageous when it is time for me to make my goals more clear, specific, and measurable by applying to certain graduate schools that specialize in Computational/Applied Mathematics.

Not only have these professors taught me about mathematics, but they have also continuously fueled my love and passion for mathematics simply by giving me opportunities to challenge myself with the mysteries of mathematics. Without the help and passion given to me by these very special teachers and mentors in my life, I do not believe that I would be pursuing a degree in mathematics and ultimately be the student that I am today.

### Paige Thibodeaux

#### Brief biography

Paige Thibodeaux is a sophomore undergraduate at Louisiana State University majoring in Computational Mathematics with a minor in Philosophy while also concurrently fulfilling premedical requirements. She is currently involved in a research group exploring the topic of Discrete Dynamical Systems and the Generation of Fractals with Dr. Frank Neubrander, and she is part of a group planning an AP Calculus Day at LSU, which is intended to assist area high school AP Calculus students in the preparation for their AP test. She also works as a caregiver for an autistic woman and spends much of her free time searching for area trails to run.

#### Mathematical and Educational Activities

My research endeavors are currently limited to my involved in research with Dr. Neubrander on the topic of Discrete Dynamical Systems and the Generation of Fractals. While I am an undergraduate, I hope to continue to expand my knowledge of the subject of mathematics through involvement in research, especially in topics with potential to broaden my understanding of mathematical biology. My teaching endeavors are similarly limited to my current involvement in a group that is planning an AP Calculus Day for area high school AP Calculus students. I also hope to be involved in tutoring for local public schools in the future as an undergraduate student.

### Jeremy Tillay

#### Brief biography

I am a 20-year old sophomore at LSU pursuing a degree in Pure Math. I am a LA-STEM Research Scholar, Honors College Student, and have been doing undergraduate research since my first semester of freshman year. I have always known that I wanted to major in math, but it was not until I started taking higher-level maths that I was certain I wanted to pursue my PhD. I have competed in two math tournaments while at LSU and won first place in both of them! Outside of school, I am a member of the Honors College Advocates, and I love literature. I enjoy reading both fiction and nonfiction. Also, I enjoy writing fiction as a hobby when I want to explore artistic interests.

#### Mathematical and Educational Activities

I tutor classmates and students in classes I have taken before regularly. So far, I have not asked for pay, as it's always been a fun activity for me that keeps my knowledge of material fresh.

As far as research, I have studied the resonance in one and two dimensional lattices under the advisement of Dr. Shipman. Studying these systems has given me insight that is now allowing me to research quantum graphs that model graphene tubes. It is my hope that I can find a way to add defects to the system that will allow for a resonant interaction in the model. This research has really helped me see higher-level math for what it is, and it has been an interesting experience to need to employ a large variety of mathematical tools to solve a problem. Computer programming, theoretical math, paper-and-pencil calculations, research into graph theory, among other efforts are what have solved these problems in the past. It's very different from completing a homework assignment that can be done in a few hours. I have to work on these problems for days and sometimes reach numerous dead ends, but I wouldn't trade it for the world. I hope that early in my senior year, I can have a paper published on carbon nanotubes.

#### Summary of current and future projects

The research I was involved in last summer at Yale is close to being ready for submission to an academic journal. I have taken some time off of my work with Dr. Nandakumar to focus on this and my work with Dr. Robert Kooima on experimental interface design. I will be building a video game to exposit my work with Dr. Kooima before leaving for Imperial College London for the summer, where I will work on problems in the unification of microfluidics at various scales.

#### Mathematical and educational activities

My mentors can be said to have formed an exact sequence, iteratively evincing my dream of eventually leading an interdisciplinary research group where I can apply my training in mathematics and computation to tackle problems in quantitative biology. Beginning my first semester at LSU, each of my mentors' disparate strengths and advice pushed me squarely into the kernel of the next, allowing me to systematically hone my interests while acquiring experience in diverse areas from approximating operator semigroups to modeling chemical signals that facilitate chromosome segregation. My background working with mathematicians, engineers, and physicists has left me ideally poised to approach my interests in biology with an interdisciplinary perspective; it has shown me how diverse problems can all be successfully approached from the unified framework of mathematical modeling. [The reader may jump to last paragraph without loss of cohesion.]

Having garnered an introduction into formal mathematics from MIT's OpenCourseWare offerings in high school, I dove into research weeks after arriving at LSU under the tutelage of Dr. Frank Neubrander. My first research project involved investigating whether new error estimates for approximating operator semigroups could be applied to more efficiently to calculate the matrix exponential, an object ubiquitous in scientific computation. Dr. Neubrander's patient exposition allowed me to fall in love with the challenges inherent in decomposing a research problem into manageable components. Specifically, I was tasked with implementing the new algorithms using Matlab, Mathematica, and pure C, and testing them for efficiency and accuracy. Although the existing methods were marginally more efficient on modern architectures, the experience of challenging the cutting edge in scientific computation primed my interest in computational science, concluding in a poster presentation at LSU's 2012 Undergraduate Research Conference.

Having focused my sights on mathematical research, I participated in the Mathematical and Theoretical Biology Institute's REU under Dr. Carlos Castillo-Chavez at Arizona State University the summer after my freshman year. Because of Dr. Castillo-Chavez's inspirational leadership and example as both a mathematician and a spokesperson, the summer experience became far more than the first experience with interdisciplinary research it was designed to be. My team (composed of three undergraduate mathematicians and a biology major) independently developed a research question pertaining to aneurysm formation and used the C++-based open source fluidics toolkit OpenFOAM to investigate whether turbulence caused by aneurysms in the Circle of Willis might influence downstream secondary aneurysm formation. A technical report on our findings was printed in the REU's internal journal. Beyond the research itself, however, I learned the importance of championing my work, giving talks at the 2013 JMM and Brown's 2013 SUMS Conference, chairing talks and presenting at the Mid-Atlantic SIAM meeting, and presenting a poster on my work at SACNAS.

Returning to LSU my sophomore year, I enrolled in graduate math classes while continuing research with Dr. Neubrander exploring applications of his work in semigroups to the computation of the Laplace transform. I again implemented and tested the new algorithms in Matlab, Mathematica, and pure C. Although they were once again were marginally less efficient than existing methods, it was for my talk on this work that I won a presentation award at LSU's 2013 Undergraduate Research Conference. I was also personally invited to give my hour-long presentation on this work for a colloquium series at Humboldt State University (a California State University).

The following summer, I was accepted into the Howard Hughes Medical Institute's EXROP program to work at Yale University under Dr. Christine Jacobs-Wagner. It was at Yale, through creating, testing, and applying mathematical models for post-replication chromosome segregation in C. crescentus, that I realized that my future was in quantitative biology. I worked alongside chemists, physicists, and biologists, and I reveled in the challenge of communicating my mathematical perspective to everyone in my lab. With the help of Dr. Jacobs-Wagner and my friend Dr. Ivan Surovtsev, I learned what it takes to succeed in biological research; I learned what it takes to convince people from various backgrounds of the utility of a mathematical perspective, a perspective of which they are often inordinately skeptical. I learned what it takes to build models that agree both quantitatively with the data you are studying and qualitatively with the established ideas of the field. We are now working on getting a paper written including the models I built over the summer.

Now that I have returned to LSU once again, it may seem that I have put aside my interests in biological research to further pursue studies in mathematics, given my heavy graduate-level course load. In actuality, I am working my way through Wade's Organic Chemistry, Watson's Molecular Biology of the Gene, and books on the cell and neuroscience in my spare time, a preparation reminiscent of my high school days learning on ocw.mit.edu that so successfully prepared me for my studies of mathematics. Further, I will be travelling to Imperial College London over the summer in preparation for my future in biological research by partaking in research in microfluidics, a phenomenon integral to almost all cellular mechanisms.

Dr. Neubrander narrowed my interests to mathematics. Dr. Castillo-Chavez taught me to be a spokesperson. Dr. Jacobs-Wagner's lab showed me the joy of applying mathematics to cutting-edge problems in quantitative biology. Individually the morphisms on my character that these influences induced have images in areas foreign to each other. However, in combination, they have provided a holistic sampling of important perspectives, all preparing me for a successful career as a researcher in computational and quantitative biology.

### Christopher Kennady

#### Brief biography

My name is Christopher Kennady; I am a sophomore here at LSU now in my second semester of Mathematics. I am the oldest of two children, I have a younger sister who is fifteen and a sophomore in high school. My passions are found in sports and the outdoors. My time is spent hunting, fishing, or just anything to keep my outside. My family and I live for LSU sports so I have bled purple and gold since the day I was born. It has always been my dream to be a Tiger and attend LSU. As a freshman I enrolled as an Industrial Engineer major but quickly I found that this is not the path I wanted to follow and felt Mathematics was my true calling. My dream job is to become a high school math teacher and to coach football along with track and field. Being able to influence young students to find their love for Mathematics along with helping young athletes everyday will be a great blessing in my life. With this goal in my sights I have begun a research project along with the guidance of Dr. Neubrander.

My name is Morgan Landry, and I am currently a 21-year-old junior at Louisiana State University from Lafayette, Louisiana. I went to Comeaux High School, where I was on the swim team, and was a member of the robotics club. After graduating, I moved to Baton Rouge, where I started studying mathematics and became a member of the Geaux Teach program. Although my parents and two younger brothers still live in Lafayette, I am extremely happy here at LSU, where I am pursuing a degree in Math/Secondary Education with a minor in Philosophy.

#### Mathematical and Educational Activities

Dr. Frank Neubrander and I are currently working to expand upon the research that I did during the summer of 2013 through the Noyce program. Last summer, my research was on the field of sequences and the z-Transform, but now I am working to expand the topic by including asymptotic cases. Each week, Dr. Neubrander and I meet to discuss my progress and talk about any questions I have regarding content I am studying. I am working toward writing a paper and re-writing my current poster to include the new material I have been researching.

After graduating from LSU, I intend to go to grad school to continue my studies and hopefully get a Ph. D in Math Education. In order to prepare myself for this, I am going to continue doing mathematical research with Dr. Frank Neubrander, and present another poster on my updated research in March. Also I plan to apply for a research position at Utah State University to conduct research on education over the summer of 2014. I believe that these experiences will give me the upper hand when applying to graduate schools and help me further understand what is to come in my future.

### Emelie Mativi

#### Brief biography

I am a junior at LSU pursuing a math major with a concentration in secondary education. I am a three year member of the Geaux Teach program as well as the Honors College. My passion for education led me to become a Noyce Scholar and commit two years to teaching in a high needs school district. I have been participating in research at LSU for over two years, and am now working on a thesis project. I received Sophomore Honors distinction and the Tiger Excellence Award. I am a member of the Distinguished Communicators program and the National Society of Collegiate Scholars. When I am not focused on school I really enjoy volunteering. I have volunteered for three years at an equestrian center for special needs children. I am also a member of the LSU quiz bowl team and love competing in tournaments. I will be student teaching in the fall of 2014, and then I will continue in pursuit of a Master's in education.

#### Mathematical and Educational Activities

I began work on my thesis last semester, but the research began over two years ago. I worked with Dr. Shipman to develop an understanding of resonance in lattice systems, and I gained understanding of advanced mathematical concepts along the way. Learning these concepts in the form of a project instead of in a traditional classroom setting gave me a deeper understanding of the material. I realized how helpful this form of teaching could be, and I wanted to attempt to develop a curriculum using it. For my thesis project I am combining my passion for math and education to produce a series of lesson plans that incorporate upper level math concepts into a high school level curriculum. I am using the same material that has been the foundation of my research throughout my college career, but I am presenting it in a geometric sense. So far, I have completed a high school unit plan that incorporates concepts such as complex variables, calculus, and trigonometry. I have also completed detailed scripts of multiple lessons, so that others can see exactly how I imagine these concepts being taught. I am going to finish my thesis this semester by completing a poster that presents the material covered in the lessons as well as how the upper level concepts were incorporated. I hope to convince other instructors that it is possible to integrate difficult concepts into the current curriculum, and I want to show how beneficial this style of teaching would be to students. I also hope that spending a year on a project like this will help me when I begin my career as a teacher.

### Mandonesia Maurice

#### Brief biography

Mandonesia Maurice is a sophomore Mathematics student at Louisiana State University. was born and raised in Kenner, LA. She attended Bonnabel High School in Kenner and graduated in the top 10 of her class. She has always dreamed of attending Louisiana State University. As a Louisiana native, Mandonesia enjoys dance, great food, music and culture. She is a member of Sigma Lambda Gamma National Sorority Incorporated, LSU's first and only multicultural sorority. Currently she is pursuing a degree in Mathematics-Secondary Education. Maurice is also a student of Geaux Teach, an organization that provides LSU students with pedagogy as well as field experience. In the near future, she plans to further her education, travel the world a bit, and teach less fortunate children. “Math is beautiful. Unlike the variation that other subjects may have in other countries, 2+2 will always equal 4.”

#### Mathematical and Educational Activities

Mandonesia applied for the Robert Noyce Undergraduate Research Experience in the spring semester of her freshman year, without any experience in research and only Calculus I knowledge. She worked with Dr. Robert Perlis, chair of the Math Department at LSU, which allowed her to secure strong ties and a head start on other Math courses at LSU. Her research utilized the Harmonic Series and Mathematical Induction, among other skills, to solve a problem. As a Geaux Teach student, Mandonesia has gained experience in teaching as well. She has taken courses directly related to pedagogy and courses exercising field experience. Maurice has taught third graders, 6th graders and is currently assigned to an Algebra II classroom. In addition to teaching the lessons, Geaux Teach students are required to plan and write their own lesson plans, so Mandonesia has experience there as well.

### Colleen Robichaux

#### Brief biography

Growing up in Houma, Louisiana, Colleen Robichaux often observed her mother preparing for lessons and seeing her mother's love for education, which inspired Colleen's own interest in education. During her freshman year at Louisiana State University where she majored in Mathematics with a concentration in Secondary Education, she began participating in an undergraduate group researching generalized functions. Finding this research quite interesting, Colleen continued the same project in an REU at Louisiana State University with Dr. Neubrander during the summer of 2012 for which Colleen produced and presented a poster twice at two LSU research conferences. Enjoying the previous REU so thoroughly, she participated in an REU at Missouri State University with Dr. Les Reid in the summer of 2013 and returned in the fall to present her research at a conference. Colleen is continuing research and tutoring and is looking forward to student teaching in the Geaux Teach program. After graduating, rather than immediately teaching in a high school, she now plans to pursue a graduate degree in Mathematics so that she may teach at a higher level.

#### Mathematical and Educational Activities

Currently, Colleen is continuing the project which she began last summer at a Research Experience for Undergraduates at Missouri State University. In this project she is researching properties of non-commuting graphs under the guidance of Professor Les Reid at Missouri State University. Colleen plans on completing this project to produce a paper and a poster, which she will present at the LSU Discover Research Day. This semester Colleen is working as an undergraduate learning assistant for a Linear Algebra and Differential Equations class, helping students develop a deeper understanding of the course material. She also continues to tutor students privately and remains in the Geaux Teach program, in which she is looking forward to student teaching.

### Avery St. Dizier

#### Brief biography

I was born right here in Baton Rouge, and I have lived here my whole life. I went to St. Aloysius for elementary school, where I joined the Boy Scouts and later became an Eagle Scout. I continued on to Redemptorist High School, where I joined Mu Alpha Theta and discovered that math was actually fun and was the thing for me. I am now a junior mathematics major here at LSU, and I am enjoying every day here. I live on campus with three other math majors, and I love the dynamic that we have when we work together and help each other out. I enjoy regular trips to the UREC with my friends for rock climbing and racquetball.

#### Mathematical and Educational Activities

In an effort to better understand the intricacies and difficulties of communicating mathematics, I regularly tutor in various subjects. I enjoy the challenge of working to convey what I know in a cohesive form to someone else. Communicating the ideas I have been taught exposes the gaps in my own understanding and helps me to consolidate my knowledge, keeping me up to date on information from classes that I might otherwise forget from disuse. Tutoring also allows me to give back to the mathematical community at LSU, which often supports me, particularly in providing opportunities for undergraduate mathematical research.

This semester I am enrolled in an independent reading course under Professor Achar. I intend to complete the groundwork for an undergraduate honors thesis project this semester and to write the thesis next semester or over the summer, time permitting. We will be studying reflection groups.

Reflections are mappings from a Euclidean space to itself that are isometries whose set of fixed points is a hyperplane. Concretely, in two dimensions, a reflection would be like folding a piece of paper. Points located along the fold line are fixed, they do not move. Points not along the fold line are sent to their mirror image across the fold. It is also easy to visualize a reflection in three dimensions: the only difference is that we reflect across a plane instead of a line. Reflections can be defined mathematically in any finite number of dimensions.

When we take a set of reflections and combine them in all possible ways, what we get is called a reflection group. It is a collection of transformations of space, each of which can be described as a series of reflections. Reflection groups have remarkable geometric and group theoretic properties. We will be exploring various topics in reflection groups and their more general counterparts, Coxeter groups.
