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 made a few iPhone photography apps that automatically aligned and merged photos. They were popular in the 2009-2011 era, and one of them (TrueHDR) 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 was acquired by VSCO and I worked at VSCO as a Director of Engineering.

I then joined Google Research in 2019.
