I am a postdoc at Microsoft Research New England. I received a PhD and MS in Electrical Engineering and Computer Science from the Laboratory for Information and Decision Systems (LIDS) at Massachusetts Institute of Technology. I received my B.S. in Computer Science from California Institute of Technology in 2011. I will be beginning as an assistant professor in the Operations Research and Information Engineering Department in Fall of 2018. Here is a current copy of my CV. |

The goal of my research is to design scalable statistical algorithms for processing social data based on principles from statistical inference. In our modern world, much of the data is generated by humans and drives decisions made in a variety of settings. Due to the complexities of human behavior, the precise data model is often not obvious, and naive assumptions could drastically effect the outcome of the analysis. This warrants the need for developing a fundamental theory for how to integrate flexible human behavioral models together with statistics and machine learning methods. Recently, I have worked on increasing the flexibility of models and algorithms through an approach of nonparametric regression for latent variable models (aka blind regression). These approaches are related to matrix completion and community detection, and have implications towards applications such as recommendation systems, denoising crowdsourced solutions, and social network analysis. Previously I have also worked on sparse matrix methods, specifically how to exploit sparsity or graph properties to approximate a single component of the solution to a linear system, or the largest eigenvector.
