About Me

I am a fourth year PhD student at Carnegie Mellon University in the Computer Science Department where I am fortunate to be advised by Nina Balcan. Before that, I completed my MSc at the University of Alberta, advised by Richard Sutton and András György.

I am interested in the theoretical foundations of Machine Learning, and especially questions about the impact of Machine Learning on society. Given the complexity of learning systems, I think one of the most promising approaches to ensuring a positive impact is to explicitly incorporate social values, like privacy, fairness, and interpretability, into our algorithms. I have ongoing projects exploring fairness in machine learning and differentially private clustering, algorithm parameter tuning, auction design, and pricing problems. I have also worked on actor-critic methods for Reinforcement Learning, Online Learning, label efficient multi-class learning, and distributed learning.

Here is my cv.

Teaching

In the Spring semesters of 2015 and 2016, I was a TA for Introduction to Machine Learning (10-601). In 2015 the course was taught by Nina Balcan and Tom Mitchell, and in 2016 it was taught by Nina Balcan and William Cohen. I received a TA Award from the Machine Learning Department for TAing 10-601 in Spring 2016.
