Research interests

Qixiang CHENG received a Bachelor's degree from the Huazhong University of Science and Technology in 2010 and a Ph.D. degree from the University of Cambridge, Cambridge, U.K., in 2014. He was a research scientist with the Lightwave Research Laboratory at Columbia University, New York, NY, USA, where he led the research effort in silicon photonic device design, layout, packaging, and testing. He was heavily involved in nationwide projects funded by ARPA-E, NSF, and DARPA in the US. In Jan 2020, he returned to the University of Cambridge as a University Lecturer and his research focuses on developing system-wide photonic integrated circuits for optical communication, sensing, and optical computing applications, exploiting a number of photonic integration platforms. He has served as a committee member for top-tier conferences such as OFC, CLEO, CLEO-PR, ECIO, MOC, and Photonics West. He is an author of more than 130 refereed journal and conference papers, including Nature Photonics, Nature Communications, Light: Science & Applications, Proceedings of the IEEE, Optica, Photonics Research, etc.

Qixiang is an elected fellow of Fitzwilliam College.
