Title
POLYMERIZATION REACTION ENGINEERING — a PERSONAL JOURNEY
ABSTRACT: Our group has been involved with the modeling of several polymerization systems: those associated with unequal (site) reactivity (ARB resoles etc.) industrial polymerizations (nylon-6 polyethylene terephthalate polymethy methacrylate polystyrene etc.) complex polymerizations (epoxies polyphenylene oxide polyimides the redistribution reaction in PET etc.). Some of the industrially important polymerization reactors have also been optimized using Pontryagin’s minimum principle and more recently using multi-objective (MO) evolutionary techniques like genetic algorithm (GA) and simulated annealing (SA). Several phenomena in nature have been mimicked to adapt multi-objective GA codes. These include jumping genes (transposons) in genetics and the altruistic behavior of honey-bee colonies. The increase in the speed of convergence with these adaptations allows their use for on-line optimal control.ABOUT THE SPEAKER: Santosh K. Gupta is currently the L & T Professor of Chemical Engineering at the Indian Institute of Technology Bombay. He has been on the faculty at IIT Kanpur since the last 37 years. A graduate of IIT Kanpur he did his PhD at the University of Pennsylvania Philadelphia in 1972. His research interests include polymerization engineering and multi-objective optimization using genetic algorithm (GA) and simulated annealing (SA). He is the author of five text books one research monograph (Plenum NY) and a co-editor of one Conference Proceedings. He has about 200 research publications in international high-impact journals and has a Hirsch’s h-index of over 23 (23 papers have over 23 citations). He is a Fellow of the Indian Academy of Sciences Bangalore the National Academy of Sciences India Allahabad and the Indian National Academy of Engineering New Delhi. He is a recipient of the Herdillia Award of the Indian Institute of Chemical Engineers for Excellence in Basic Research in Chemical Engineering. He has also been a Visiting Professor in the Departments of Chemical Engineering at the National University of Singapore (1998-99) University of Wisconsin at Madison (1999-2000) and at the University of Notre Dame (1985-1987).
