I am a second-year CS Ph.D. student at the University of Wisconsin-Madison, advised by Prof. Kirthevasan Kandasamy. I am broadly interested in Machine Learning. My current research focuses on developing efficient learning algorithms for active learning and multi-armed bandits.

Before that, I obtained my B.Sc. in Data Science and Analytics from the National University of Singapore in 2020. I was fortunate to work with Prof. Vincent Y. F. Tan on Nonnegative Matrix Factorization.
