Curriculum Vitae

Google Scholar

I am a third-year CS Ph.D. student at the University of Wisconsin-Madison. I am broadly interested in Machine Learning and Data Science.

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.
