ABOUT

I’m a Computer Science Ph.D. student at New York University, advised by Prof. Rumi Chunara. I also work closely with NYU Langone. Currently, I work with Amazon as an Applied Scientist Intern, advised by Prof. Hengrui Cai and Dr. Rui Song. I finished my master’s and bachelor's at Seoul National University, advised by Prof. Sanghack Lee. Before my doctoral studies, I was a Researcher at LG AI Research.

I am primarily interested in Foundation Models, broadly in understanding its out-of-distribution generalization. I am enthusiastic about a wide range of subjects, including:

• Foundation Models for safety-critical domains (e.g., Healthcare)

• Continual Learning for Foundation Models

• Post Training (e.g., Weight Space Operations, Model Collaboration, Reasoning)

• Causal Representation Learning & Causality-inspired Generalization Algorithms

Apart from research, I’m a big fan of History👨🏻‍🏫 and Jazz🎷. I'm also interested in the application of Artificial Intelligence to humanities research (e.g., Histoinformatics). Please feel free to reach out for multi-disciplinary research collaborations!
