Chengying received his PhD in optics from Tsinghua University in 2016. He then worked as a postdoctral researcher at Purdue University. His previous work focused on the generation of frequency combs, arrays of evenly spaced optical frequencies. At Caltech, he will work on using this light source for rapid and sensitive methane leak detection, which may advance the technology for use with natural gas energy sources.
Chengying is currently an assistant professor at Tsinghua University
