About Me

I am a PhD candidate at TTIC, working under the supervision of Gregory Shakhnarovich. I'm mainly interested in computer vision and applications of machine learning to machine vision problems. Specifically semantic segmentation, 2D & 3D scene understanding, and structured prediction.

Before coming to TTIC, I received my master's degree from the Department of Computer Science at Brown University under the direction of Michael Black.
