I lead a team developing AI/ML features for Pixel Computational Photography. We deliver end-to-end solutions across engineering and research boundary.
Short Bio
I received my Ph.D. from MIT CSAIL in 2015, advised by Frédo Durand and Bill Freeman on Computational Photography, Computer Vision, and Computer Graphics. My PhD research was about data-driven graphics. By leveraging repetitive visual-information and high quality examplars, my thesis explores advanced image editing algorithms. I've worked on hardware devices for imaging and enhancement during my master in MIT. Before Google, I was a Research Scientist at LightCo, where we launched the very first (and super cool) L16 camera (Verge).
Luckily, I had great intern opportunities to work with Jon Barron and Marc Levoy (Google[x], 2014), Sylvain Paris and Connelly Barnes (Adobe Research , 2013), Vivek Kwatra and Troy Chinen (Google Research , 2012) Neel Joshi and Brian Guenter. (Microsoft Research, 2011). I am always happy to work with talented interns. Please contact me if you are interested in doing an internship with me. I have been lucky to work with the following interns so far:
-
Kai-En Lin: from UCSD, on Object NeRF (2021)
-
Chen Gao: from Virginia Tech, on Portrait NeRF (2020)
-
Zixun Yu: from Purdue, on portrait image enhancement (2019)
-
Wei-Shang Lai: from UC Merced, on wide-angle portrait distortion correction (2018)
