Short Biography:

Dr. Peter Qiang Liu is currently an Associate Professor of Electrical Engineering at University at Buffalo, the State University of New York. Prior to his appointment at UB since 2017, he held a postdoctoral researcher appointment at Sandia National Laboratories, working on metamaterials-enhanced light-matter interactions in semiconductors and strongly correlated electron materials. Before that, he was a postdoctoral research fellow at the Institute for Quantum Electronics and the Department of Physics at ETH Zurich (October 2012 to September 2015). His work at ETH Zurich focused on developing graphene-based tunable THz and MIR plasmonic and metamaterial structures for various device applications.

Dr. Liu obtained his Ph.D. in Electrical Engineering from Princeton University in September 2012. His PhD work focused on developing high-performance Quantum Cascade lasers employing novel quantum and laser cavity designs. He received his B.E. in Electronic Engineering with highest honor from Tsinghua University, Beijing, in 2007.
