I'm a fourth year Ph.D. candidate at the University of Minnesota in the Department of
Computer Science and Engineering. My advisors are
Arindam Banerjee and
Maria Gini. I was a visiting student
last summer at the Australian National University where I was advised by
as part of the NSF 2013 East Asia and Pacific Islands Summer Institutes Fellowship.
I'm broadly interested in Artificial Intelligence and Machine Learning.
In particular, my focus has been on online learning algorithms, convex
optimization, adversarial learning models, and recommender systems. The
application areas I have worked in are finance (portfolio selection), climate
science (forecasting), internet content serving (news article recommendations),
and cancer genomics.
