I am an assistant professor at the Department of Computer Science and the Department of Information Science (by courtsey) 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.

Michael Macy, Daniel Romero, Amit Sharma and I are organizing the first workshop on "Beyond Online Data: Tackling important social science questions" at ICWSM in Stanford, CA on Jun 25. Please submit or participate (submission deadline: Apr 22)!

Current course: Human-centered Machine Learning (blog).

Openings: 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:

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