Curriculum Vitae

Contact: hanchcao AT stanford.edu

Hi! I am a final year PhD candidate in Department of Computer Science, Stanford University (with a PhD minor in management science and engineering), working with Prof. Daniel McFarland and Prof. Michael Bernstein. I am affiliated with Stanford HCI group and Stanford NLP group .

During my PhD, I have interned at Office of Applied Research, and Computational Social Science Group at Microsoft Research, and Semantic Scholar Team at Allen Institute for Artificial Intelligence. I have also collaborated with Prof. Melissa Valentine and Prof. Julien Clement.

I received my bachelor degree (with honors) from Department of Electronic Engineering, Tsinghua University in 2018. In the past, I was fortunate enough to work under the supervision of Prof. Yong Li at Tsinghua University, Prof. Vassilis Kostakos at University of Melbourne, Prof. Hanan Samet at University of Maryland, Prof. Alex 'Sandy' Pentland at MIT Media Lab, and Prof. Xiaowen Dong at University of Oxford.

My research interests encompass computational social science, social computing, and human-AI interaction, with a specific emphasis on their applications within the context of the future of work. Bridging computation and social science theories, my works seek to unravel the intricacies of work dynamics and interactions through mining large-scale data with state-of-the-art computational methods, complemented by qualitative evidence and system building. My works have won three best paper/best paper honorable mention awards at top conferences in human-computer interaction, including CHI, CSCW. My works have also appeared in top social science journals, e.g. American Sociological Review, and reported in venues such as Wired, Forbes and TED. My research is supported by Stanford Interdisciplinary Graduate Fellowship.

I am on the job market this year! I will graduate with my PhD degree in spring 2024. I'm open to tenure track faculty positions or relevant industry roles. Please get in touch!

    Honors and Awards

    Academic Service



    I have passions for a wide variety of fields, and I am constantly exploring new areas and possibilities. Some of my major interests include:

    Classical Music

    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!
