He received his PhD working under supervision of Dr. Ali Shakouri at University of California at Santa Cruz in 2004, worked at MIT as postdoctoral scholar under supervision of Drs. Mildred Dresselhaus and Gang Chen, and worked at Oklahoma State University as Assistant Professor in 2008-2013. He is an expert in superlattices and nanostructured materials for energy conversion and sensing applications. In the past, he has contributed to the development of several key thermoelectric structures including heterostructure thermionic devices and bulk nanocomposite thermoelectric materials. He is the recipient of the NSF CAREER award and the Goldsmid Award for research excellence in thermoelectrics from the International Thermoelectric Society.
