About
I'm a Ph.D. student in Computer Science and Engineering at Penn State University, advised by Prof. Wenpeng Yin.
My research interests include how agents can understand user intent clearly, reason with minimal overhead, and act adaptively in ambiguous situations. My goal is to develop AI systems that combine structured reasoning with personalized behavior, enabling accurate and cost-effective collaboration with humans.
