I am a Ph.D. student at ECE department, Purdue University. I joined Professor Gerhard Klimeck's NEMO (Nanoelectronic Modeling) group as a Graduate Research Assistant in August 2012. Earlier I served as a Lecturer in Electrical and Electronic Engineering (EEE) of Bangladesh University of Engineering and Technology (BUET) since March 2011 immediately after completion of my Bachelor of Science from same Department in February. My job there was to instruct undergraduate students different basic courses (both theory and laboratory) in the fields of Electronics, Communication, Computer etc in their Freshman and Senior years.
