Dr. Li received a B.E. from Tsinghua University and a Ph.D. from Georgia Institute of Technology. His doctoral research focused on developing optical signal processing technologies in both silicon and silicon nitride platforms. After graduation, he worked as a CNST/UMD postdoctoral researcher in National Institute of Standards and Technology. His work at NIST developed techniques for chip-scale quantum frequency conversion, octave-spanning microresonator frequency combs for optical frequency synthesis, and photonic interfaces for interrogating rubidium atomic systems. For his work, Dr. Li has received the Outstanding Graduate Student (Colonel Oscar P. Cleaver) Award and Sigma Xi Best Ph.D. Thesis Award from Georgia Institute of Technology. He also won the Sigma Xi Most Outstanding Poster and PML Distinguished Associate Award while at NIST. Since joining CMU, Dr. Li is also a recipient of the Darpa Young Faculty Award (2019) and 2020 OSA Paul F. Forman Team Engineering Excellence Award.

The general interest of the group is to study light and matter interactions that can be realized in an integrated photonics platform. One particular focus is on the nonlinear aspects of such interactions, which is a key enabling factor of many photonic technologies. In addition, it plays an increasingly important role in emerging fields such as quantum information processing and quantum computing. Using advanced nanofabrication and optical designs, the group aims to develop novel photonic materials/devices on the chip scale for classical and quantum information processing.
