Irfan Bulu [irfan@seas]
Bio
Dr. Bulu received his B.S., M.S., and Ph.D. degrees in physics from Bilkent University. His M.S thesis was concentrated on Radiation Properties of Sources Inside Photonic Crystals. In 2003, he was rewarded full scholarship for his Ph.D studies in physics by Bilkent University. His doctoral study involved Photonic Crystals, Metamaterials, and Surface Plasmon Phenomena. He later joined Professor Loncar’s lab as a postdoctoral researcher.
