I am an assistant professor of Computer Science at Princeton University. Previously, I was a visiting scientist at Facebook AI Research (FAIR) in Seattle. I received my PhD from the Computer Science Department at Stanford University, where I was advised by Christopher Manning and worked in the Stanford NLP Group.
Before that, I was an undergraduate student from the Special Pilot CS Class supervised by Andrew Yao at Tsinghua University.
My main research interests lie within deep learning for natural language processing, and I am particularly interested in the intersection between text understanding and knowledge representation/reasoning.
Prospective students: I am actively looking for strong students to join our group! If you are interested in working with me, please apply through the Princeton CS PhD program and mention me in your application (and I can't respond to all the individual emails).
If you are already admitted to Princeton, feel free to reach out.

- My name is pronounced as "dan-/'chE/" (read this). My friends like to call me "CDQ" though.
- I come from Changsha, China. In the past, I have also lived in Beijing, Hong Kong, Palo Alto, New York, Boston and Seattle.
- Here are two papers that I wrote in high school (in Chinese):  and  and they are known as "plug-like dynamic programming" and "CDQ's divide-and-conquer" today.
- Whenever I am not thinking about research, I enjoy most of outdoor activities and also spend a lot of time on reading, movies & exploring restaurants.
