About

I am currently a PhD student at the Computer Science Department at Carnegie Mellon University, where I am advised by Prof. Christos Faloutsos and Prof. Ruslan Salakhutdinov. My research interests are in the area of Deep Graph Learning.

More specifically, I’m interested in Automation and Democratization of Graph Learning using various deep learning techniques. My recent work includes automation in 1) polishing/generation of graph structures, 2) generation of node/edge/subgraph representations, and 3) solution generation in the application level. Ultimately, I’d like to empower all users to benefit from their own graph structures, regardless of their level of expertise in the graph learning field.

I was a research intern at Amazon.com, LinkedIn, and Google Research. Before joining CMU, I received my bachelor’s and master’s degrees from Seoul National University, South Korea.

Research opportunities: I am usually looking for students to help with research projects both during the semester and over the summer. If you are interested, please send me an email. I especially encourage students from underrepresented groups to reach out.
