overview

Dr. Rahimian is an assistant professor of Industrial Engineering at the University of Pittsburgh, where he leads the Sociotechnical Systems Research Lab and is also affiliated with the Intelligent Systems Program (ISP) and the Institute for Cyber Law, Policy, and Security (Pitt Cyber). Prior to that, he was a postdoc with joint appointments at MIT Institute for Data, Systems, and Society (IDSS) and MIT Sloan School of Management. He received his PhD in Electrical and Systems Engineering from the University of Pennsylvania, and Master’s in Statistics from Wharton School. Broadly speaking his works are at the intersection of networks, data, and decision sciences. He borrows tools from applied probability, statistics, algorithms, as well as decision and game theory. Some of his current focus is on the challenges of inference and intervention design in complex, large-scale sociotechnical systems, with applications ranging from online social networks, public health, e-commerce and collective decision/action platforms to modern civilian cyberinfrastructure and future warfare. He is especially interested in the critical role that information plays in the operation of sociotechnical institutions and its societal implications, particularly related to privacy, fairness and information integrity (e.g., issues of social learning and spread of misinformation and other harmful content). He has served on the program committee of the 2021 ACM Economics and Computation conference and the 2022 IISE annual conference (as the operations research track co-chair), and is currently serving on the advisory council of the vaccine confidence fund (a new industry alliance), as well as the program committees of EAAMO'22 (Equity and Access in Algorithms, Mechanisms, and Optimization), SocialSens2022 (Special Edition on Information Operation on Social Media), 2023 ACM Economics and Computation conference, 2024 Web Conference, 2024 Privacy-Preserving Artificial Intelligence workshop (PPAI), 2024 Theory and Practice of Differential Privacy workshop (TPDP), 2024 Annual Modeling and Simulation Conference (as the US and Canada publicity chair), and 2025 PPAI and Web Conference. He has published in the Proceedings of the National Academy of Sciences, Nature Human Behaviour, Nature Communications, the Operations Research journal, the Automatica journal, and several IEEE Transactions. At Pitt he has tought or is teaching Stochastic Processes (IE 2084), Foundations of Statistics (IE 2117), Design of Experiments (IE 1072), Advanced Topics in Operations Research (IE 3080, focusing on probabilistic analysis of algorithms and randomized algorithms), and a new engineering elective called "Data for Social Good" (IE 1171) that he has developed as part of the Pitt Year of Data and Society initiative.
