I am interested in the fundamentals and applications of light propagation. On the technology side, I develop laser systems that range from diode-pumped Ti:sapphire oscillators to high power ultrafast amplifiers. Coherent beam propagation, control and characterization have been a long-term interest. This includes exotic forms of structured light: spatial and temporal focusing, vortex beams, and Bessel-Gauss beams. We use linear interferometric and nonlinear tools to characterize the properties of these beams. Nonlinear dynamics of beam propagation in free space (filamentation) and guided waves (solitons and continuum generation) are active areas in which we are working. We strive to couple our experimental measurements with theoretical analysis and computational modeling.
