Brief Intro.

I'm an assistant professor at University of Memphis. I obtained Ph.D. in Information Science (advised by Dr. Michael J. Paul and Prof. Robin Burke) @ the University of Colorado Boulder. Previously, I graduated from the Chinese Academy of Sciences with MSc. in Computer Science.

My current research interest is in domain adaptation, user modeling & transfer learning, with applications in health informatics. For example, I modeled and analyzed public health issues (flu vaccination services and mental health) via social media. I also had some experience in cross-lingual transfer learning of low resourced languages.

In my free time (due to COVID-19, the volunteering activities have stopped for years), I enjoy hiking and doing volunteering works. I volunteered in YMCA, One Heartland, local nursing house & HIV organization, etc. I love cooking and traveling.


Email me if you plan to work with me.
