Areas of Expertise:

Basic research experience in electromagnetic and optical field theory, wave propagation phenomena, and applied mathematics.

Specific research interests include asymptotic analysis, the frequency- domain and time-domain representations of electromagnetic, optical, and acoustic wave fields, electromagnetic properties of dielectric, conducting, and semiconducting materials, diffraction and scattering theory, coherence theory, the rigorous description of dispersive pulse propagation in both linear and nonlinear media and waveguiding structures, nonlinear optics, and laser physics.

Applied research interests in ultrawideband-signal, ultrashort-pulse electromagnetic field characteristics, impulse radar systems, image formation and analysys, stable and unstable open optical cavity mode properties, optical beam transfer systems, adaptive optics, integrated optics devices, and fiber optics communications systems.
