About Me
I’m currently a Research Scientist Intern at Meta Superintelligence Labs, where I work on agentic red-teaming for multi-service ecosystems. Before joining Meta, I completed my Ph.D. at the Graduate School of AI, KAIST, under the supervision of Prof. Eunho Yang at the Machine Learning and Intelligence Lab.
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).
