Some thoughts on Carl Adam Petri, Petri nets, concurrency theory and biology
P.S. Thiagarajan received a B.Tech from the Indian Institute of Technology, Madras (1970) and a PhD from Rice University, Houston (1973). He has held academic positions at MIT, Cambridge, GMD, St.Augustin, Aarhus University, The Institute of Mathematical Sciences, Chennai, the Chennai Mathematical Institute and the National University of Singapore (NUS). After retiring from NUS (2015), he spent 3 years at the Laboratory of Systems Pharmacology, Harvard Medical School as a visiting professor. He is a currently a senior research scientist at the Department of computational and systems biology, University of Pittsburgh.
Over the years, his research interests have ranged over Petri nets, concurrency theory, temporal logics, controller synthesis, real-time embedded systems, hybrid automata and probabilistic dynamical systems. During the past 10 years, his main focus has been computational systems biology.
