Shahadat Sohel joined NREL in 2020 as a postdoctoral researcher in the Material Sciences Center. His current research focuses on developing electronic devices and sensors based on wide bandgap semiconductors applicable for harsh operating conditions such as high temperature and mechanical stress.

He received his bachelor's and master's degrees in electrical and electronic engineering from Bangladesh University of Engineering and Technology  in 2012 and 2015, respectively. He then received his doctorate in electrical and computer engineering from The Ohio State University in 2020. While pursuing his doctorate, he worked on developing high frequency, RF power amplifiers for high-linearity applications based on III-Nitride materials.
