I am a Professor at the University of Pennsylvania.
I study supply chain management, operation strategy and pricing with a focus on how technology transforms competitive dynamics and enables novel business strategies.
I am an INFORMS Fellow, a Fellow and former President of the Manufacturing and Service Operations Management Society, and the former Editor-in-Chief of Management Science as well as Manufacturing & Service Operations Management.
I have authored two textbooks (along with Christian Terwiesch): Operations Management (1e) and Matching Supply with Demand: An Introduction to Operations Management (4th ed.). These books have been used in undergraduate, MBA and executive MBA courses at Wharton as well as at numerous other business schools throughout the world.
My articles have appeared in Management Science, Manufacturing & Service Operations Management, Marketing Science, Operations Research, the Quarterly Journal of Economics, and Harvard Business Review, among others.
As Vice Dean of Teaching and Strategic Initiatives I develop and lead new initiatives for enhancing Wharton's excellence in teaching and research.
