Hi, I'm a final-year computer science PhD student at Georgia Tech, advised by Polo Chau.
My research on "Human-Centered AI through Scalable Visual Data Analytics" focuses on building novel data visualization tools for helping people explore, interpret, and interact with machine learning systems, by combining methods from data visualization, machine learning, databases, data mining, and human-computer interaction.
I have been supported by a Google PhD Fellowship and an NSF Graduate Research Fellowship. During my PhD studies, I have been fortunate to work with amazing people at Google Brain and Facebook Research, resulting in publications and open-sourced and deployed systems.
Prior to Georgia Tech, I completed both my master's and bachelor's degrees at Seoul National University in South Korea.
