I am a researcher at Adobe Research where I research in image generative models and efficient deep learning (CV). Before that, I got my Ph.D. in the Department of Electrical and Computer Engineering at Princeton University in Novemeber 2022, fortunately supervised by Prof. Sun-Yuan Kung and Prof. David Wentzlaff. I received my BEng in Electronic and Computer Engineering from Hong Kong University of Science and Technology (HKUST) in June 2017.

I spent two wonderful summers at Adobe Research working with Dr. Zhixin Shu, Dr. Yijun Li, Dr. Zhe Lin, Dr. Richard Zhang, and Dr. Federico Perazzi in 2020 and 2021. Adobe Research is open to university collaboration in forms of internship and joint projects for motivated students. If you are interested in doing research projects with me, please drop me an email with your CV.
