If you are interested in grad school at Wash U, or potential postdoc / visitor / intern positions in my group, please read this page before contacting me.


I am part of the fantastic and growing Machine Learning and AI group at Wash U CSE. I have broad interests across AI, machine learning, and computational social science. Recently I have worked mainly on designing effective algorithms for agents in complex, uncertain environments, and on understanding the social or collective outcomes of individual behavior. My research spans market microstructure, matching markets, social networks, reinforcement learning, sequential decision-making, supervised learning, and data mining. For more details, you can read some of my papers.

Professional Bio

Sanmay Das is an associate professor in Computer Science and Engineering and the chair of the steering committee of the newly formed Division of Computational and Data Sciences at Washington University in St. Louis. He is vice-chair of the ACM Special Interest Group on Artificial Intelligence, a member of the board of directors of the International Foundation for Autonomous Agents and Multiagent Systems, and serves on the editorial board of the ACM Transactions on Economics and Computation. Dr. Das has served as program co-chair of the AAMAS and AMMA conferences and area chair for AAAI, in addition to regularly serving as a senior program committee member of major conferences including IJCAI, AAAI, EC, and AAMAS. He has been recognized with awards for research and teaching, including an NSF CAREER Award and the Department Chair Award for Outstanding Teaching at Washington University. He has worked with the US Treasury department on machine learning approaches to credit risk analysis, and occasionally consults in the areas of technology and finance.


  • September 2018 (sticky!): I am super-excited to announce the new Division of Computational and Data Sciences at WashU. I am the steering committee chair, and chair of the Computational Methodologies track for the division. We are looking for strong Ph.D. applicants for our first cohort to start in Fall of 2019.

  • November 2018: Looking forward to visiting USC CAIS to hear more about all the amazing work they are doing, and give a seminar.

  • November 2018: Happy to have been named a Distingished Senior Program Committee Member for IJCAI 2018!

  • October 2018: Two one-day trips to Boston in two weeks, one for the MIT LFE conference on Interpretable Machine-Learning Models and Financial Applications (where I talked about measuring partisanship from text data!), and one to attend GroszFest, celebrating the life and work of the amazing Barbara Grosz, one of my undergraduate mentors, first co-author, and mentor to so many in our field.

  • August 2018: I joined the editorial board of the ACM Transactions on Economics and Computation as an associate editor.

  • June 2018: I enjoyed meeting the young scholars of the macro financial modeling project and talking to them about machine learning and finance at the summer session.

  • May 2018: Honored to be elected to a 6-year term on the board of directors of IFAAMAS.

  • May 2018: Had a great visit to RPI to give a colloquium talk, and hear what the terrific machine learning / EconCS faculty and students there are up to.

  • February 2018: I gave a What's Hot Talk at AAAI, highlighting some of the best work presented at AAMAS 2017

  • January 2018: Gave a really fun tech talk on machine learning to 400+ folks at Mastercard!

  • Recent service: I was PC co-chair of AAMAS 2017, an Area Chair for AAAI 2018, and on the SPC for AAMAS, IJCAI, and EC.

  • April 2017: Mithun just defended his terrific dissertation!

  • Assorted Audio/Video and Media Coverage

  • Recording of an interview with Jay Kanzler on KTRS where I talk about search, bias, algorithms, and society.

  • I talked about machine learning for credit risk on a techemergence podcast.

  • Videos of a session in which I gave the second talk and interview I gave on prediction markets at the Microsoft Research Faculty Summit are online (along with a ton of other interesting talks and interviews!)

  • The Wikimedia research newsletter of September 2013 discussed some of our work on manipulation in Wikipedia

  • An INFORMS Daily Report blog post from 2008 on some of our Wikipedia research

  • An article from The Economist in 2003, describing some of my research on modeling financial markets
