Hi! I am a fifth year PhD candidate in Department of Computer Science, Stanford University (with a PhD minor in management science and engineering), advised by Prof. Dan McFarland and Prof. Dan Jurafsky. In previous quarters, I rotated with Prof. Michael Bernstein and Prof. Jure Leskovec, and collaborated with Prof. Melissa Valentine and Prof. Julien Clement. I am affiliated with Stanford NLP group and Stanford HCI group.
I received my bachelor degree (with honors) from Department of Electronic Engineering, Tsinghua University in 2018. I studied as an exchange student in A. James Clark School of Engineering, University of Maryland, College Park in Fall 2016.
I have been a research assistant in Future Communications and Internet Lab, Tsinghua University, advised by Prof. Yong Li and Prof. Vassilis Kostakos (University of Melbourne) since 2015. In Fall 2016, I was fortunate enough to work under the supervision of Distinguished University Professor Prof. Hanan Samet at University of Maryland. In Summer 2017, I was a visiting student and research assistant at Human Dynamics Group, MIT Media Lab, advised by Prof. Alex 'Sandy' Pentland and Prof. Xiaowen Dong.
My research interests broadly lie in computational social science, social computing, and data science.News: [Apr 2023] Paper on analysis of patent citation to HCI research received best paper award at CHI'23!

I was a member of Tsinghua Student Art Troupe Clavier team and served as vice captain in 2015 and 2016. I have been playing classical piano since 2001 and attained the highest level for amateur player in 2008. I also play the trombone and attained the highest level in 2007.
I enjoy works by Ludwig van Beethoven (who provides me with immense power when I'm feeling down), Johannes Brahms, Franz Schubert, J.S. Bach, Claudio Monteverdi, Anton Bruckner, Gabriel Fauré, Claude Debussy and Alexander Scriabin. Glenn Gould, Yehudi Menuhin, Sergiu Celibidache, Maria Callas are some of my favourite interpreters.Right now I am studying Harpsichord at Stanford on a Stanford Friends of Music Scholarship.
I enjoy British poems, Chinese modern literature, visual arts (painting, sculpture and architecture), history and social science. I am especially passionate about the field of social history (where I have drawn inspirations for my research).
I am also keen on sharing my knowledge with others. I was captain of volunteer docents at Shanghai Soong Ching-ling Memorial Residence in 2012 and 2013.
I enjoy swimming (I was a member of Tsinghua EE swimming team), jogging, tennis and working out. Currently I am learning Taekwondo and Karate, and I plan to start on rock climbing and camping.Ping me if you are interested as well!
