Dr. Guanquan Liang’s research field is in photonics and optics, with interdisciplinary efforts extended to material science and condensed matter physics. He joined Prof. Thomas group since Oct. 2014 for PT-symmetry photonic systems. Prevoiusly he has successfully addressed several topics, including: Laser interference lithography for important photonic micostructures, Optical analog of topological insulators, and Tunable resonant modes based on photonic crystals.
