Qiushi Guo, Ph.D.

  • Assistant Professor, Photonics Initiative
  • Assistant Professor of Physics, CUNY Graduate Center

The Guo group seeks to uncover new physical principles underlying the interaction between light and emerging active photonic materials, and to harness the resulting unprecedented optoelectronic properties in a scalable way to tackle the grand challenges in classical and quantum information processing, optical computing and mid-infrared sensing. Our future research directions include:

  1. Integrated ultrafast light sources and novel architectures for unconventional photonic computing;
  2. Next-generation thermal vision technologies and
  3. Quantum interactions between light and emerging materials.

Prior to joining the ASRC and the CUNY Graduate Center, Qiushi was a postdoctoral research associate at the California Institute of Technology. He received his Ph.D. in Electrical Engineering from Yale University in 2019. He received his M.S. degree in Electrical Engineering from the University of Pennsylvania in 2014, and his B.S. degree in Electrical Engineering from Xi’an Jiaotong University in 2012. Qiushi is named a finalist for the 2022 Rising Stars of Light and the winner of the 2021 Henry Prentiss Becton Graduate Prize for his exceptional research achievements at Yale University. His research interests include integrated ultrafast and quantum photonics, mid-infrared photonics, and optoelectronics in emerging quantum materials. He has published more than 40 peer-reviewed research papers in leading scientific journals and holds 2 US patents. He is serving on the editorial board of the journal Micromachines.

Postdoc and Ph.D. positions are available. Please contact Professor Guo by email for more information.
