Raihan joined Lo Group in Fall 2015 after moving to US for his PhD study. He earned his B.S. and M.S. in Electrical and Electronic Engineering (EEE) from Bangladesh University of Engineering and Technology (BUET) in 2013 and 2015 respectively. His research focuses on modeling, design, fabrication and characterization of the single photon detector.
