About
My research goal is to accelerate materials discovery with AI. I am particularly interested in closed-loop discovery, where AI generates candidate materials, evaluates them through property prediction and simulation, learns from experimental feedback, and is orchestrated by AI scientists that run the loop autonomously. I am interested in every component of this loop and in connecting them into a single discovery system.
