I now work at Georgia Tech as a Postdoc under Dhruv Batra, Devi Parikh and Irfan Essa.

I got my PhD in Brown University working with Erik Sudderth in computer science department. My research interests are computer vision with applications in 3D scene understanding and computer graphics with applications in image manipulation. I did my undergrad in mathematics at Zhejiang University.
