Welcome to my mathematics website.
My research concerns the mathematics that arises in the study of waves in composite
The problems I investigate concern the following topics.
Link to PUBLICATIONS. Here are some recent works on the Fermi surface:
- Spectral theory of differential and integral operators
- Electromagnetic resonance; meta-materials
- Coupled nonlinear dispersive systems; polariton equations

Research experiences for undergraduates
By carefully selecting projects, mentoring undergraduates can be rewarding for student and mentor. Read about the projects of my students at the REU link. Some of them are
- Toy Model for Density of Bound States
- Misconceptions in Vector Calculus
- Structure vs. Spectra for Quantum Graphs
- Modes and Resonance in Anisotropic Media
- Lattice Model for Metamaterials
Math Consultation Clinic
In the MCC, graduate students manage teams of undergraduate students in problems from other disciplines and research entities and companies on and off the LSU campus.
Opportunities for undergraduate students
This link lists opportunities for undergraduate mathematics majors to become involved in research. We encourage our majors to begin early. Students may contact me about this. Take a look at some of the current PROJECTS in mathematics that involve undergraduates.
My mathematics studies transpired at the University of Arizona in Tucson.
Under the direction of Prof.
Nicholas Ercolani an increasing number of years ago, I completed my Ph.D. on the topic "A continuum limit of a finite discrete nonlinear Schrödinger system."
This is my trajectory anti-chronologically:
