About Sohrab Asgarpoor

Dr. Asgarpoor is professor of Electrical and Computer Engineering. In July 2017, he accepted the position of interim associate dean for undergraduate programs in the College of Engineering and was named associate dean in August 2018. 

From 1985 to 1986, he worked as a lecturer in the Department of Electrical Engineering at Texas A&M University. In 1986, he joined ABB Network Management Technology Inc., Houston, Texas (formerly Ferranti International Controls Corp.) as a senior engineer, where he designed and developed advanced power system applications software for energy management systems. Since September 1989, he has been with the University of Nebraska-Lincoln. His research involves mathematical modeling, simulation, optimization, and reliability evaluation of electric power and energy systems including Distributed Generation (DG) toward the goal of improved decision making under uncertainty.
