I am an assistant professor of Computer Science at Princeton University. Previously, I was a visiting research scientist at Facebook AI Research (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 always looking for strong students. If you are interested in working with me, please apply through the Princeton CS PhD program (and I can't respond to all the individual emails).

- 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.
- Some of my portraits: 1, 2, 3 (credit: Lu Wang).
- I am on Twitter.
