I'm a Ph.D. student
Amherst working in
Extraction and Synthesis Laboratory with
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 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.
I am also the chief designer and maintainer
of ReSearcher.cc, a
database of scientific affiliations and collaborations
and conference management. Our backend integration
engine dynamically produces ReSearcher's content by
synthesizing multiple sources of data including edits
from users. ReSearcher has been used by ICCV, ECCV,
CVPR and MICCAI to help identify conflicts of interest
in peer review and automatically produce matchings of
papers to reviewers. I'm also helping to transition
ReSearcher's data and functionality to

Other Fun Stuff
In my spare time, I enjoy cooking (especially
ethnic foods that involve
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
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.
