Research

My research interests are in computer vision, graphics, and machine learning. I have been working on 3D capture and tracking, geometry representations, stochastic structures, image/video processing, rendering, animation, interpreting structures learned by neural networks, and sampling techniques for imaging, capture, and machine learning.
