About Me
“Embrace light. Admire it. Love it. But above all, know light.” — George Eastman
I am a Postdoctoral Research Scientist in the Lightwave Research Laboratory at the Columbia University in the City of New York, supervised by Prof. Keren Bergman. I design large-scale integrated photonic systems to transform future computing paradigms. Addressing communication bottlenecks in AI/machine learning applications through embedded photonic I/O and heterogeneous integration, I aim to redefine chip-to-chip connectivity with unparalleled density and novel functionalities beyond data communication.
I obtained my Ph.D. degree in Electrical and Computer Engineering from the University of California, Santa Barbara, in 2021, co-advised by Prof. Kwang-Ting Cheng and Prof. John E. Bowers. I earned my B.Eng. degree in Electronic Engineering from Tsinghua University, Beijing, China, in 2015.
🕵️♂️ I am seeking tenure-track faculty positions starting in Fall 2025. Feel free to contact me at yw3831 [at] columbia [dot] edu.
