I'm a Ph.D. student at UMass Amherst working in the Information Extraction and Synthesis Laboratory with Professor Andrew McCallum. I work on designing efficient and large-scale learning algorithms, especially with applications to entity resolution and, more generally, clustering. I'm broadly interested in machine learning, scalable algorithms, dynamic data structures and crowdsourcing. I have recently taken up a significant interest in issues related to fairness and machine learning systems.

About Me

I received a B.S. in Computer Science from Tufts University and worked as a researcher at MIT Lincoln Laboratory building intelligent decision support systems for US intelligence analysts. I spent the summer of 2014 at Google MTV training models of worker-task interaction that I used to optimize a new crowdsourcing platform. I spent the summer of 2016 at Google NYC building deep networks to predict attributes of the locations in Google Maps.

Researcher.cc

I was the chief designer and maintainer of ReSearcher.cc, a database of scientific affiliations and collaborations and conference management. Our backend integration engine dynamically produced ReSearcher's content by synthesizing multiple sources of data including edits from users. ReSearcher was used by ICCV, ECCV, CVPR and MICCAI to help identify conflicts of interest in peer review and automatically produce matchings of papers to reviewers. The tool is no longer supported, but its functionality has been implemented in OpenReview.net, a fully-featured and customizable conference management tool, which I am also involved with.

Other Fun Stuff

In my spare time, I enjoy cooking (especially ethnic foods that involve uncommon spices), learning for free, climbing, playing soccer and other sports, composing/playing music, fermenting things, snowboarding, playing German-style board games, traveling the world, listening to NPR (e.g. The Moth Radio Hour and wNYC's RadioLab), eating gummy candy, and learning about philosophy, food systems, religion, and nutrition.

In a previous life, I was a varsity college soccer player, I co-found a start-up and was a junior olympic Tae Kwon Do champ.

My favorite book is Zen and the Art of Motorcycle Maintenance.
