Professor Roels is an Assistant Professor at the UCLA Anderson School of Management. His research interests are in supply chain management and in operations management in knowledge-based services.

In his research, Professor Roels has characterized the worst-case performance of supply chains with limited demand information and uncoordinated decision-making. His findings have led to the development of principles for making robust supply chain decisions, such as contracting, capacity investment, capacity allocation, and pricing. In addition, he has studied how to improve productivity in knowledge-based services, by properly designing incentive mechanisms or improving time management. His research has been published in journals such as Management Science, Operations Research, Manufacturing & Service Operations Management, and Production and Operations Management and led to several research awards.

At UCLA, Professor Roels teaches the core course on operations management for the MBA and Executive MBA programs, executive courses on revenue management and entrepreneurship, as well as a doctoral course on inventory theory. He was presented with numerous teaching awards, both student-voted and faculty-selected.
