Dr. Ke Xu will join Rochester Institute of Technology as a tenure-track Assistant Professor in the School of Physics and Astronomy and program faculty in Microsystems Engineering in August 2021. He is currently 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 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 started to work with Prof. Susan Fullerton-Shirey in 2014 at University of Notre Dame as a post-doctoral researcher, where he worked on the development of low-voltage and steep subthreshold swing components for beyond-CMOS electronic systems. He moved to University of Pittsburgh during 2016 as a research faculty. 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.
