IISER Mohali organized jointly with the Santa Fe Institute (SFI), USA, the first India Complex Systems Winter School, where 61 participants from Australia, Bangladesh, China, France, Hungary, Mexico, New Zealand, The Netherlands, UK, USA and India participated. Given the interdisciplinary nature of the topic, participants ranged from young faculty in management studies, policy research to undergraduate students in biology and computer science. The intensive two-week course was taught by 11 faculties from different Institutions in USA and associated with the SFI, and 5 from India. The aim of the course was to introduce the methodology to study complex behavior in mathematical, physical, living, and social systems. The theoretical lectures consisted of nonlinear dynamics, network theory, statistical physics and complex networks, computational complexity, agent based computational economics, ergodicity economics, econophysics, social network analysis of human behavior, cognitive science and social minds, evolution of gene networks, microbial ecology, and infectious disease. There were extensive discussions among the participants and faculty, who also organized evening tutorials and discussions on relevant papers and mathematical tools. Professor Somdatta Sinha was the course director.
