Ke Xu is an Assistant Professor in the School of Physics and Astronomy and Microsystems Engineering at Rochester Institute of Technology. Previously, he was a Research Assistant Professor at the University of Pittsburgh and served as the Executive Director of the Pittsburgh Quantum Institute (PQI). He received his BS in Optical Engineering from Zhejiang University, China, and his PhD in Electrical Engineering from the University of Illinois in Chicago. He then worked as a postdoctoral researcher at the University of Notre Dame, focusing on the development of low-voltage and steep-subthreshold swing components for beyond-CMOS electronic systems. Since joining RIT in 2021, he has established the Iontronic and Nanoelectronic Lab (XuGroupRIT.com), where his research explores next-generation energy-efficient electronic devices at the limits of scaling, with a focus on memory, logic, neuromorphic computing, and novel computing architectures for AI-driven applications.
