electric field magnitude

Welcome to my mathematics website.

My research concerns the mathematics that arises in the study of waves in composite media.
The problems I investigate concern the following topics.

  • Spectral theory of differential and integral operators
  • Electromagnetic resonance; meta-materials
  • Computation of quasi-periodic Green functions for electromagnetics
  • 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.

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:

Professor, Louisiana State University (2014-)
Visitor, Institute for Mathematics and its Applications, Minneapolis, MN (Fall 2016)
Associate Professor, Louisiana State University (2008-2014)
Visiting Researcher, Universidad Carlos III, Madrid (Fall 2010)
Research Scientist, Courant Institute, NYU (2006-'07)
Visiting Professor, Institut Élie Cartan, Nancy, France (summer, 2006)
Assistant Professor, Louisiana State University (2002-'08)
Visiting Assistant Professor, Duke University (2001-'02)
Assistant Research Professor, Duke University (-2001)
Ph.D, University of Arizona, advisor: Nicholas Ercolani
