Yuanzhen Li

I completed my PhD (2009) at MIT with Prof. Edward H. Adelson. At MIT, I was a member of the Computer Science and Artificial Intelligence Laboratory (CSAIL) and the Perceptual Science Laboratory. I've worked at MERL, Adobe, and Microsoft Research Asia, on computer vision and machine learning projects.

I then spent a few years in quantitative finance. I also made a few iPhone photography apps that automatically aligned and merged photos. They were popular in the 2009-2011 era, and one of them was an inaugural member of Apple's "App Store Hall of Fame".

I then founded a small company focusing on visual discovery using computer vision and machine learning. It recently got acquired by VSCO and I now work at VSCO as a Director of Engineering.
