Before Boulder, I was a postdoctoral researcher at University of Washington, working with Noah Smith for a year. Prior to that, I spent wonderful years at Ithaca working with Lillian Lee and many others, and obtained a PhD degree in Computer Science at Cornell University. Originally, I am from Jingdezhen, China and lived in Beijing for four years while studying Computer Science and Economics at Tsinghua University.

You are here probably because you are interested in learning about life trajectories. I have a paper on that subject, and the main takeaway is "People, unlike trees, thrive by relocation".

If you are looking for a formal bio, here is the most recent one:
Chenhao Tan is an assistant professor of computer science at University of Colorado Boulder. He obtained his PhD degree in the Department of Computer Science at Cornell University and bachelor's degrees in computer science and in economics from Tsinghua University. Prior to joining CU Boulder, he spent a year at University of Washington as a postdoc. His research interests include natural language processing and computational social science. He has published papers primarily at ACL and WWW, and also at KDD, WSDM, ICWSM, etc. His work has been covered by many news media outlets, such as the New York Times and the Washington Post. He also won a Facebook fellowship and a Yahoo! Key Scientific Challenges award.
