I am an assistant professor at the Department of Computer Science and the Department of Information Science (by courtesy) at University of Colorado Boulder. You can learn more about my life trajectory here.

My main research interests include

  1. Language and social dynamics.

  2. Multi-community engagement, how a person interacts with multiple communities and how communities relate to each other, e.g., users' life trajectories, community genealogy, and migrant integration in urbanization.

  3. Human-centered machine learning, how we can use machine learning to empower humans and augment human intelligence such as enhancing creativity and avoiding behavioral biases, e.g., creative writing with a machine in the loop.

I am also broadly interested in computational social science, natural language processing, and artificial intelligence. Here is my CV.

Openings:

I am looking for a postdoc.

I am looking for motivated students who are interested in NLP, data science, computational social science, or machine learning! Please read this FAQ before contacting me.

Demo systems:

  • Reddit genealogy, visualize the genealogy between Reddit communities.
  • retweetedmore, predict which tweet is going to be retweeted more.
  • TReMoLoop, text revision with a machine in the loop. Try to write a slogan!
