Director, Center for Advanced Studies in Photonics Research (CASPR), Professor of Computer Science & Electrical Engineering (CSEE) and Professor of Physics
Uses ultrashort pulse lasers to investigate the ultrafast photophysics and nonlinear optical properties of bulk, nanoscale and quantum well semiconductor structures, ultrashort pulse propagation in fibers and novel waveguide structures and high-speed lightwave systems. As Deputy Director of the NSF Engineering Research Center (ERC) MIRTHE (Mid-Infrared Technologies for Health and the Environment) [2006-2016], our group uses femtosecond mid-infrared pulses of light to study the gain dynamics and nonlinear optical properties of active quantum cascade lasers (QCLs) and other mid-infrared devices. Recent research involves the use of ultrashort pulses of light for laser-induced inactivation of murine norovirus samples, which are a leading cause of food-borne illness. Collaborative discussions are underway to utilize laser- enhanced thermal imaging to detect breast and prostate cancer tumors in mouse models.
