Dr. Peter Qiang Liu joined University at Buffalo Electrical Engineering in January 2017 after completing a postdoctoral research appointment at Sandia National Laboratories, working on metamaterials enhanced light-matter interactions in semiconductors and strongly correlated electron materials. Previous to that, he was appointed as 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 there focused on developing graphene-based tunable THz and MIR plasmonic and metamaterial structures for various device applications.

He obtained his PhD in Electrical Engineering from Princeton University in 2012. His thesis work focused on developing high-performance Quantum Cascade lasers employing novel quantum and laser cavity designs. He was awarded the Francis Robbins Upton Fellowship and the Harold W. Dodds Honorific Fellowship for his graduate study at Princeton University. He received his BE in Electronic Engineering with highest honor from Tsinghua University in 2007.
