About

I am currently a final 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

Graphs are ideal tools to depict relationships between discrete entities. Deep Learning on Graphs (DLG) enhances understanding of each entity by considering its interactions with other entities. As graph data continues to expand in scale and diversity, DLG algorithms are required to evolve under unprecedented constraints, such as privacy guarantees for end-users or different modalities for entities (e.g., text, images). My past and current research have focused on making DLG algorithms more : to address this evolving data landscape. Going forward, my goal is to understand the interplay of different modalities toward developing unified approaches that can holistically address multimodal datasets with their relations.

🔈 I am on the job market this year.
