Bio

Dr. Ke Xu is an Assistant Professor in the School of Physics and Astronomy and in Microsystems Engineering at Rochester Institute of Technology. Previously he was a Research Assistant Professor at University of Pittsburgh and Executive Director of the Pittsburgh Quantum Institute (PQI). 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 at Chicago working with Prof. Michael Stroscio and Prof. Mitra Dutta. His doctoral research focused on graphene- and DNA aptamer-based micro/nano scale electronic devices and their applications in photodetectors and biomolecular sensing. He worked as a post-doctoral researcher with Prof. Susan Fullerton-Shirey at University of Notre Dame on the development of low-voltage and steep subthreshold swing components for beyond-CMOS electronic systems. His current research interests include two-dimensional (2D) materials-based nanoelectronic devices, with the focus on understanding ion-electron transport at the molecular level, for application in next-generation energy-efficient electronic devices at the limit of scaling for memory, logic, energy storage, neuromorphic computing, and quantum information science.
