I am a third-year Computer Science Ph.D. student at Carnegie Mellon University and am supported by an NSF graduate research fellowship. I spent the first two years of my Ph.D. working between mobile systems and applied machine learning and I now work with Zico Kolter on machine learning and optimization. I am particularly interested in improving our understanding of important modeling problems in computer vision, language, and reinforcement learning through the use of deep learning, optimization (sometimes convex), theory, and statistics.

As an example, we’ve recently been exploring the intersection of deep learning and convex optimization with input convex neural networks (ICNNs): neural networks that are convex with respect to some of the inputs. Our preprint is available at arXiv:1609.07152 and shows applications to multi-label classification, image completion, and continuous-action reinforcement learning.

I strongly believe in open science and reproducible research and actively publish code on my Github profile. I am also the author of OpenFace, which is an open source face recognition project that uses deep learning.
