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. 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., human predictions along a spectrum between full human agency and full automation, human preferences of task delegation to AI, and creative writing with a machine in the loop, and the meta question of what tasks humans would like to delegate to AI systems, and to what extend.

  3. 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.

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

I am teaching Human-centered Machine Learning in Spring 2020.

Openings:

I am always looking for motivated postdocs and PhD students who are interested in NLP, data science, computational social science, or machine learning! I am moving to the University of Chicago in January, 2021. Please apply to UChicago CS if you are interested in working with me. Please read this FAQ before contacting me.

Reviewing requests:

I am declining all new reviewing invitations until May 2021. Unfortunately, I have over-committed myself to reviewing/organization service. I will need the time to read these interesting submissions in my queue.
