Biography

 

Cheng received his B.S. degree in Microelectronics from Tsinghua University in 2012. Afterwards, he joined Harvard University as a PhD student in the School of Engineering and Applied Sciences, advised by Prof. Marko Loncar. He received his Ph.D. degree in Electrical Engineering in May 2017, and is now a postdoctoral fellow in the Loncar group. Cheng's research focuses on enhancing light-matter interaction in nanophotonic structures. In particular, Cheng is interested in the miniaturization of lithium niobate photonic devices and their applications in optical communications and nonlinear optics.
