Justin Morris, Ph.D.

Justin Morris recieved his Ph.D. degree from University of California, San Diego and San Diego State University in 2022. He had the pleaure of being advised by both Dr. Tajana Rosing and Dr. Baris Aksanli. Before starting his Ph.D. degree, Justin was an undergraduate student researcher at the University of California, San Diego. He finished his B.S. in 2018 and took a gap year focusing on research while he applied for his Ph.D. to stay in Dr. Tajana Rosing's research group, System Energy Efficiency Lab. During both his undergraduate and graduate degrees, Justin was activly engaged in teaching. He worked as a Tutor, TA, and also an Instructor at the University of California, San Diego. Justin recently joined California State University, San Marcos as an Assistant Professor of Computer Engineering in Fall 2022.
