Qiangfei Xia | Electrical and Computer Engineering | UMass Amherst

Brief Bio

Dr. Qiangfei Xia is a professor of Electrical & Computer Engineering at UMass Amherst and head of the Nanodevices and Integrated Systems Lab . He received his Ph.D. in Electrical Engineering in 2007 from Princeton University, where he was a recipient of the Guggenheim Fellowship in Engineering (a graduate fellowship from Princeton). He then spent three years as a research associate in the Hewlett Packard Laboratories in Palo Alto, California, during which time he demonstrated the first CMOS/memristor hybrid chip with reconfigurable logic functions. In October 2010, he joined the faculty of UMass Amherst as an assistant professor (tenure clock started in January 2011). He became an associate professor with tenure in January 2016 and then a full professor in September 2018.
Dr. Xia's research interests include beyond-CMOS devices, integrated systems and enabling technologies, with applications in machine intelligence, reconfigurable RF systems and hardware security. Recently, with his team, he developed a reliable multilevel Ta/HfO2 RRAM device that meets most of the required device properties for in-memory computing in artificial neural networks, the world's smallest memristive devices in a crossbar circuit (2 nm feature size, 6 nm half pitch), and the tallest 3D crossbar array (8 layers) as a convolutional neural network for video processing. Furthermore, he integrated then largest analog memristive crossbar arrays (chip image featured as the inaugural cover of Nature Electronics), and demonstrated a wide variety of applications in analog computing, machine learning and hardware security. Finally, he debuted the first nanoscale memristive RF switch with superior performance, and a few novel hardware security primitives such as a robust true random number generator and a versatile crossbar array that integrates memory, computing and hardware security functionalities. He has received a DARPA Young Faculty Award (YFA), an NSF CAREER Award, and the Barbara H. and Joseph I. Goldstein Outstanding Junior Faculty Award.
Dr. Xia teaches freshman to graduate level courses, including Introduction to Electrical and Computer Engineering (ENGIN 112), Semiconductor Devices (ECE 344), Microelectronic Fabrication (ECE571) and Nanostructure Engineering (ECE 597/697NS). He was nominated for the Distinguished Teaching Award (DTA), a campus-wide highest honor to recognize exemplary teaching at UMass.
Dr. Xia serves as a technical committee member for the IEEE International Electronic Devices Meeting (IEDM), IEEE International Symposium on Circuits and Systems (ISCAS), International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication (EIPBN, steering committee 2019-25; conference chair 2023), co-program chair for the 14th International Conference on Nanoimprint & Nanoprint Technology (NNT), to name a few. He organized the in-memory computing tutorial session at the 2019 IEEE International Memory Workshop (IMW) and served as a guest editor or on editorial board for a number of journals. He is also an active panelist for U.S. and international funding agencies, and a peer reviewer for a few dozen international archival journals and conferences. Within UMass, his most notable service is the building of a brand new clean room facility in the Marcus Hall.
