About

I do research in the intersection of statistics, differential geometry and deep learning. I am a senior machine learning scientist at Butlr, CA. I was an applied Scientist at Amazon Lab126. I was a member of the CVGMI group at University of Florida (UF).

I joined UF–Gainesville in 2013 and finished my PhD in April 2018, where I was advised by Baba Vemuri. After my PhD, I continued my research at UF as a postdoctoral associate for 6 months and then spend 1.5 years at UC Berkely.

Research

See my research agenda for details on my current work. I am always looking for collaborations. If you're interested in working with me, email me.
