About Me
I’m currently a Research Scientist Intern at Meta Superintelligence Labs, where I work on agentic red-teaming for multi-service ecosystems. I received my Ph.D. in AI from KAIST, advised by Prof. Eunho Yang, and subsequently continued my research at the Machine Learning and Intelligence Lab as a Postdoctoral Researcher.
Research Interests
My research focuses on reliable multimodal and agentic AI, with an emphasis on (I) reliable multimodal AI, where I develop training-free methods for robust visual reasoning and study multimodal safety and fairness (with Viet Dac Lai, Adobe Research); (II) self-improving agents, which learn from failures through preference optimization and acquire new skills from experience (with Ninareh Mehrabi and Sina Shaham, Meta Superintelligence Labs); and (III) agentic red-teaming, which identifies safety risks across multi-service workflows and develops defenses for reliable deployment (with Ninareh Mehrabi, Meta Superintelligence Labs).
