Babak Heydari is a Professor in the College of Engineering at Northeastern University and Core Faculty at the Network Science Institute. His research lies at the intersection of network science, complex systems, engineering system design, and artificial intelligence. He studies the design and governance of sociotechnical systems composed of interacting human and AI agents, with particular emphasis on how network structure, information environments, and behavioral dynamics shape collective intelligence, cooperation, resilience, social norms, and system-level risk. His current work examines multi-agent systems involving large language models, human–AI collaboration, and AI-mediated platforms, with applications in engineering design, innovation systems and organizational adaptation, public health, supply chains, and digital ecosystems. He previously served as President of the Council of Engineering Systems Universities (CESUN) and, for five years, as Chair of the Scientific Advisory Committee for the Future Resilient Systems program at ETH Singapore. He  currently serves as an Associate Editor of Systems Engineering and the ASME Journal of Mechanical Design. He received his M.S. and Ph.D. in Electrical Engineering and Computer Sciences from the University of California, Berkeley, and is a recipient of the National Science Foundation CAREER Award.
