Bio

Dr. Denizel received her PhD in Decision and Information Sciences (1993) from Warrington School of Business at the University of Florida (UF).  Since then, she worked at different academic capacities in the Warrington School of Business (UF), the Graduate School of Business at Sabanci University (Istanbul-Turkey), and Özyegin University (Istanbul-Turkey) where she served as the Dean of the Faculty of Business between 2013-2016. In 2016 she joined Iowa State University, Ivy College of Business, Department of Supply Chain Management.

Dr. Denizel works in the area of Operations Management. Her current research interests focus on sustainable operations and product recovery systems through which she aims to contribute to the highly critical issue of sustainable use of scarce resources.  She also continues her research in mathematical modelling and production lot sizing.  Her previous works include flexible manufacturing and interdisciplinary research in marketing and operations, organization studies and technology management. Her research appeared in various journals, including Operations Research, Naval Research Logistics, Production and Operations Management, Operations Research Letters, Computers and OR, European Journal of Operations Research, Journal of the Operational Research Society, INTERFACES, Journal of International Research in Marketing, Decision Sciences, IIE Transactions, International Journal of Production Economics, Transportation Journal and Journal of Business Logistics. 

Dr. Denizel teaches operations and supply chain management, business process analysis and design, management science applications, and linear optimization and extensions. She has taught in MBA, Executive MBA and PhD programs and was actively involved in several Executive Education programs.
