Yuanzhen Li

At Google Research, I support a talented team and a few cross-team Computer Vision and Generative AI efforts. Recent work includes: Generative Product Imagery, "Imagen" in Google Cloud Vertex AI, Muse, DreamBooth, DreamBooth3D, Generative Uncrop, etc.

Prior to Google, I spent 10 years in the startup world. I made iPhone computational-photography apps, and one of them (TrueHDR) was quite popular in the 2009-2012 era. I also founded a startup leveraging deep learning for image search; it was acquired by VSCO in 2015 and I then worked at VSCO as a Director of Engineering.

Prior to that, I completed my PhD in 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.
