Roshanak Shafiiha received her B.S. degree in Electronics Engineering in 1997.  She then obtained M.S. degree in Electrical Engineering in 1999 from the University of Southern California. Currently she is a Ph.D. student in Electrical Engineering, working under supervision of Professor John O'Brien in Microphotonic Devices Group of the University of Southern California. Her research is on design and fabrication of photonic crystal slab waveguides, as well as theoretical and experimental analysis of superprism phenomena in 1D and 2D photonic crystals, and its applications in beam-steering.
