Ke Xu

Department of Chemical & Petroleum Engineering
Ph.D. in Electrical Engineering, University of Illinois
Summary:

Ke Xu is a Research Assistant Professor at University of Pittsburgh, and Executive Co-Director of the Pittsburgh Quantum Institute. He received his B.S. in Optical Engineering and Optoelectronics from Zhejiang University in China, and his Ph.D. in Electrical Engineering from University of Illinois, with his doctoral reseach focus on electrochemical and optical detection of ions using graphene- and DNA aptamer-based biosensors. Ke started to work with Prof. Susan Fullerton-Shirey in 2014 at University of Notre Dame, and moved to University of Pittsburgh during 2016.  His current research interests include two-dimensional (2D) material based nanoelectronic devices, with the focus on understanding ion-electron transport at the molecular level for application in next-generation electronic devices at the limit of scaling for memory, logic, and energy storage.
