Hello, I'm a/an

I'm Yubin, a final year PhD student at MIT Media Lab and a student researcher at Google Research .
My research objective and interest lies in Health AI, Agents, and AI Safety.
Specifically, I'm interested in bridging the gap between the Agent/Robot and Healthcare, delivering Personalized and Long-term interventions.
I am on the job market this year!

Updates

2026

Feb Gave an invited talk on "Towards a science of scaling agent systems: When and why agent systems work?" at the AI Talks with NTU & NUS. I enjoyed the discussions that followed, especially on how we can coordinate agents with different capabilities and the trade-offs between capability and cost 🎙️.
Jan Gave an invited talk on "Agent Scaling Law" at Adobe Research . I enjoyed the insightful discussions that followed, especially on how we can approach evaluation for agent systems and architectural design 🎙️.

Projects

My experience has been focused on implementing personalized technology with foundation models for human-agent interactions in an intuitive and reciprocal manner. Specifically, I am interested in developing personal agents that can maintain long-term interactions with humans in the wild and perform continual learning.
