301 Haking Wong Building

The University of Hong Kong

I am currently a Postdoctoral Fellow at WeLight Lab and Imaging Systems Lab, Department of Electrical and Electronic Engineering, HKU. I am fortunate to be supervised by Prof. Edmund Y. Lam and Evan Peng.

I received my Ph.D. degree in Computer Science from University of Illinois Urbana-Champaign in 2023, advised by Prof. Alexander Schwing and mentored by Prof. Viktor Gruev and David Forsyth. Before that, I completed my undergraduate study at University of California, Berkeley, where I majored in Computer Science, Applied Mathematics, Cognitive Science and Linguistics.

My research interests span the fields of Computer Vision, Computer Graphics and Computational Optics. I am particularly attracted to topics related to 3D/4D reconstruction, unconventional visual modalities (event streams, polarization, hyperspectral, etc.), AR/VR and deep optics. My non-research interests include science (fantasy/speculative) fictions, zoos and gaming.
