Prof. Hua-Jun Chen received his PhD from the School of Physics and Astronomy, Shanghai Jiao Tong University, China, in 2015. He is currently a full professor at the School of Mechanics and Photoelectric Physics at Anhui University of Science and Technology. His research interests are optical transmission properties in hybrid micro-nano systems, including hybrid cavity optomechanical systems and hybrid nanomechanical resonator systems, and the induced quantum optical phenomena, such as Fano resonance, optomechanically induced transparency, and fast and slow light effects.
