Currently, my main area of research is Photonic Crystals.  As I was beginning a Postdoctoral Research appointment at the University of Texas at Dallas, I was hired in August of 2000 as a full time consultant by Optical Switch Corporation to perform basic research and product design on photonic crystal devices. While at OSC, I implemented a comprehensive computational suite for photonic crystal research, including multiple customized FDTD routines, and a MPI-based parallel-computing FDTD routine to model extended structures such as 3D photonic crystal waveguides and long fiber optic tapers. I also had the privilege of receiving guidance from one of the pioneers of photonic crystals, Dr. John Joannopoulos of the Massachusetts Institute of Technology, who was a frequent consultant with our research group at OSC.

I worked with Optical Switch for nearly two years before they cancelled the project, at which time I returned full time to my Postdoctoral Research position at UTD. While at UTD, I set up a parallel-computing cluster to continue my research in Photonic Crystals. I also worked with periodic diffractive structures, including Frequency Selective Surfaces (FSS) and Sub-Wavelength Structures (SWS).

For those persons without a technical background who may have stumbled across this page, my research consists of studying how light interacts with a periodic structure such as a diffraction grating. One may think of a diffraction grating as a window screen, except that the "screen openings" are very small, on the order of one micrometer (one millionth of a meter), and the light under consideration is of infrared wavelength. By properly choosing the geometry of the openings, such as the shape and size, one can construct various types of optical and infrared filters.
