I'm Hangdong, a CS Ph.D. at University of Wisconsin-Madison, advised by Prof. Paraschos Koutris. I'm a member of the UW-Madison Database Group. I have broad interests in Database Systems. So far, my work has been focusing on theory and practice of query optimization.

Previously, I got my B.Sc. in Mathematics from the National University of Singapore in 2020. I was fortunate to work with Prof. Jonathan Scarlett on neural architecture search.
