About

I am currently a 5th year PhD student at the Computer Science Department at Carnegie Mellon University, where I am advised by Prof. Christos Faloutsos and Prof. Ruslan Salakhutdinov. My PhD is supported by the Amazon Graduate Research Fellowship and the Kwanjeong Educational Foundation Scholarship. I was a research intern at Amazon, LinkedIn, and Google Research. Before joining CMU, I received my bachelor’s and master’s degrees from Seoul National University, South Korea.

Research summary: My research interests are in the area of Deep Learning on Graphs (DLG). More specifically, I’m interested in making DLG more practical across four dimensions:
  • Automation: automate algorithm search and hyperparameter tuning under the message-passing framework (AutoGM)
  • Generalization: enable existing DLG algorithms specialized to molecule graphs to generalize to diverse types of graphs
  • Scalability: sample neighbors to regulate the computation cost while filtering out noisy neighbors adaptively for a task (PASS)
  • privacy: redefine conventional problem definitions, including graph generation and transfer learning, to be aware of the privacy-restricted nature of real-world graphs (KTN, CGT)
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.
