I am a first-year Ph.D. student in Informatics at The Pennsylvania State University under the supervision of Dr. Fenglong Ma. Before that, I earned my M.S. in Computer Science at Johns Hopkins University and B.Eng. in Computer Science and Engineering at Tsinghua University, Yao Class.

My research focuses on multimodal large language models (MLLMs) and Vision–Language–Action (VLA) models, emphasizing multimodal grounding and reliable decision-making for embodied AI.
