Me
I'm deeply interested in how GenAI can transform the future of photography. I was a researcher at Adobe with the computational photography team led by Marc Levoy. We were building a software-defined camera app leveraging computational photography and machine learning. I received my Ph.D. in Computer Science, advised by Ren Ng. Prior to Berkeley, I got my B.S. from Rice University with a focus in computer vision under supervision of Ashok Veeraraghavan. When I am not with my computer, I bring a (now film) camera almost whereever I go. I was born and raised in Beijing.

Photography

I love taking photos of streets, people, and random visual attractions. I've been mostly using an iPhone and a film camera. Some of my albums on Flickr.

Here are some of my favorites from recent years.
