Mark Lewis received his undergraduate degree in Mathematics and Political Science from Eckerd College in 1992, his Master’s Degree in Theoretical Statistics from Florida State University in 1995, and a Ph.D. in Industrial Engineering from the Georgia Institute of Technology in 1998. After receiving his doctorate, Lewis spent a year at the University of British Columbia as a postdoctoral fellow in the Center for Operations Excellence. He joined Cornell as an Associate Professor in 2005 after teaching Industrial and Operations Engineering at the University of Michigan.Lewis’ research interests are in Stochastic Processes with an emphasis on queueing theory. His thesis work was in this area with Professor Hayriye Ayhan and Professor Robert (Bob) D. Foley and used Markov Decision Processes to uncover some new ideas in trunk reservation and bias optimality. As a postdoctoral fellow, he worked with Martin L. Puterman and explained implicit discounting in bias optimality relating it to controlled queueing systems. Most recently, Professor Lewis has become interested in parallel processing and how resources are allocated dynamically in such systems. He is also working on fundamental advances in average cost Markov decision processes with Eugene Feinberg.
