About

I expect to graduate in May 2020. I am on the job market and looking for a research position. Feel free to contact me if your department is hiring! Here is my Curriculum Vitae.

I am a fifth year Ph.D. candidate in The Department of Computer Science at
The University of Colorado Boulder, advised by Dr. Qin Lv and Dr. Chenhao Tan. I am also working closely with Dr. Richard Han and Dr. Shivakant Mishra.

My research lies at the intersection of computational social science and ubiquitous computing, with an emphasize on bridging the gap between online and offline relationships for advancing the understanding of human behavior and society. I develop computational frameworks and ubiquitous computing systems to explore this direction. The findings of my research also offer evidence and insights for theories in social sciences.

I am also generally interested in data science, recommender systems, and natural language processing.

Miscellaneous

In my free time, I am a big sports fan. I am closely following the NBA, NFL, NCAA College Football, and English Premier League and have attended many live games. I am more fascinated by unique individuals than particular teams. The sports personalities I am currently paying attention to are José Mourinho, Lonzo Ball, and Josh Rosen.

You read this section until this line probably because you are also interested in sports. I have two CSCW papers closely related to this subject. In the first paper, , we provide a large-scale NBA fan community characterization on Reddit. In the second paper, , we leverage the existing structure of NBA-related discussion forums on Reddit to study how intergroup contact relates to intragroup behavior.
