Profile Picture

I am currently a Human-AI Researcher. In the past, I was a full-stack developer, and I aspire to become an entrepreneur in the future. My present research is centered on the design of collaboration systems that facilitate human interaction with AI-driven Programming Tools. Additionally, I am focusing on Social Computing Systems that promote community building and engagement on online social medias.

I am pursuing my Thesis-based Master's in Computer Science at the University of Waterloo, mentored by Dr. Jian Zhao of the WatVis Lab at UWaterloo. In the past, I was guided by Dr. Zhicong Lu from DEER Lab and Dr. Can Liu of the ERFI Lab at CityU HK. After obtaining my Master's, I would like to continue on a PhD journey, continuing my research in Human-AI Interaction & Social Computing.

Current State

I am open to collaborating on research projects and actively seeking a PhD opportunity.
