Haoyu Wei

512 Chow Yei Ching Building, The University of Hong Kong

I am a fourth-year Ph.D. student at the University of Hong Kong (HKU) in the Imaging Systems Lab and WeLight Lab. I am fortunate to be advised by Prof. Edmund Y. Lam and Prof. Evan Peng.

My academic journey has been driven by a passion for computational imaging, with a particular focus on deep optics. My research revolves around co-designing optical systems and inverse algorithms, leveraging deep learning networks. I also specialize in optical numerical simulations to model light propagations.

Before joining HKU, I completed my master’s degree at Northwestern University, where I worked in Prof. Oliver Cossairt’s Comp Photo Lab. My work spans sparse CT reconstruction, light field holographic rendering, and deflectometry for 3D surface profiling.

Outside research, I’m a sports enthusiast — marathons, tennis, and the gym keep me energized. Thriller is my favorate type of movies.
