Professor Sen's research is devoted to the theory and applications of large scale optimization algorithms, especially those arising in stochastic programming. He has also applied these methods to practical problems arising in airlines, electric power, mining, telecommunications and transportation. He has authored or coauthored over fifty publications, many of which have appeared in journals like JOTA, Mathematical Programming, Mathematics of Operations Research, Management Science and Operations Research. He has also coauthored a research monograph on Stochastic Decomposition . His research has been funded by federal agencies as well as industry. He has been an invited and plenary lecturer at numerous universities and conferences.
Professor Sen has served on the editorial board of several journals, the most prominent of which was his service as the Optimization Editor for Operations Research . He also served as an Associate Editor for INFORMS Journal on Computing (1995-2002) and Telecommunications Systems (1992 - 2000). He has served as guest editor for several journals ( Annals of Operations Research, COAP, IIE and Interfaces ). Professor Sen is a former Chair of the INFORMS Telecommunications Section and founded the INFORMS Optimization Section.
