I am a second-year Ph.D. student in Information Studies at the School of Information, UT Austin, working in the AI Health Lab under the supervision of Professor Ying Ding. Before joining Professor Ding’s team, I collaborated with Doctor Yi Bu at the Department of Information Management, Peking University.
My aspiration is to become a computational social scientist to uncover patterns and solutions in healthcare and scholarly communications. I am eagerly looking forward to an academic career that combines research and teaching after completing my Ph.D.
My Chinese name is 许家伟.

February 2025: I developed an interactive knowledge graph visualization, which has been adopted by the NIH Common Fund’s Bridge to Artificial Intelligence (Bridge2AI) program and featured on their official landing page. For more details, please see my paper “Demo: Interactive Visualization of Semantic Relationships in a Biomedical Project’s Talent Knowledge Graph” and explore the visualization itself.
