Larry P. Ritzman was the first Thomas J. Galligan, Jr. Professor in Operations and Strategic Management, joining Boston College in 1991. He previously served at Ohio State University, beginning in 1968. He recently concluded his service at Boston College, thus becoming professor emeritus at both Ohio State University and Boston College. He continues writing textbooks and research articles in the field of operations management, with occasional teaching opportunities. He received his doctorate at Michigan State University, and had prior industrial experience at the Babcock and Wilcox Company.

He served in various editorial capacities for the Journal of Operations Management and Production and Operations Management. He was elected as Fellow of the Decision Sciences Institute in 1987, received three best paper wards, and was selected for the Distinguished Service Award in 1996. His publications have appeared in such journals as Computers and Operations Research, Decision Sciences, European Journal of Operational Research, Interfaces, Journal of Behavioral Decision Making, Journal of Operations Management, International Journal of Operations and Production Management, International Journal of Production Research, Journal of Operational Research Society, Harvard Business Review, Management Science, Managerial and Decision Economics, OMEGA, and Operations Research. He was co-editor of Disaggregation: Problems in Manufacturing and Service Organizations. Professor Ritzman is a co-author with Lee Krajewski and Manj Malhotra of Operations Management: Processes and Value Chains (8th edition) and Foundations of Operations Management (1st edition). These textbooks will be translated into Chinese, French, Japanese, Italian, Korean, and Spanish. There is also a Canadian version of the Foundations book, co-authored with Lee Krajewski and Robert Klassen.

His early research interests were applying modeling techniques and decision support systems to problems in operations management. Recent work has moved into empirically based research, with particular interest in service processes, operations strategy, process choice, and supply chain management. Bringing judgment into the forecasting process has been an ongoing research interest.
