Santanu S. Dey joined the faculty of the Stewart School of Industrial and Systems Engineering as an assistant professor on July 1, 2009.

Since 2007, Dey has worked as a research fellow at the Center for Operations Research and Econometrics (CORE) of the Catholic University of Louvain in Belgium. His research interests are in the areas of large-scale optimization, mixed integer programming, and applications of discrete optimization in logistics and computational biology.

The results of Dey's recent research, a paper entitled "Two Families of Facets for the Two-Dimensional Mixed Integer Infinite Group Problem," will be published in a forthcoming issue of Mathematics of Operations Research, a publication sponsored by the Institute for Operations Research and the Management Sciences (INFORMS). In 2007, Dey was honored with First Place in the INFORMS George Nicholson Paper Competition for his paper entitled "Sequential-Merge Facets for High Dimensional Infinite Group Problems."

Dey obtained his Ph.D. in Industrial Engineering from Purdue University in 2007 after earning his M.S. in Industrial Engineering from the university in 2003. In 2000, Dey completed his undergraduate studies in mechanical engineering at Mumbai University, receiving Kulapati's Gold Medal for standing first among engineering students.
