Professor Nelson received a BA in Mathematics and Computer Science from DePauw University and a MS and PhD in Industrial Engineering from Purdue University. Professor Nelson is interested in the design and analysis of computer simulation experiments, particularly issues of statistical efficiency (such as variance-reduction techniques), multivariate output analysis (such as multiple-comparison procedures and optimization via simulation), multivariate input modeling (such as modeling and generation of nonstationary arrival processes) and metamodeling. He also works on approximation techniques for networks of nonstationary queues. His application areas include financial engineering, computer performance modeling, quality control, manufacturing and transportation systems. He is a Fellow of INFORMS.
