Tolga Tezcan

Associate Professor of Management Science and Operations


BS (Bilkent) MS (Colorado State) MS PhD (Georgia Tech)

Dr Tolga Tezcan’s research focuses on how to design and control service systems under uncertainty with applications in customer service systems and healthcare systems.  He has worked with  customer call centres, customer service chat systems, emergency departments, and hospital transporter systems. He has won the NSF Career Award in 2010.

Dr Tezcan’s work has been published in Management Science, Operations Research, Manufacturing & Service Operations Management, Annals of Applied Probability, and other journals.

He teaches MBA courses on Decision and Risk Analysis and a PhD seminar on Queueing Theory. He has taught MBA courses on Operations Management at University of Rochester prior to joining LBS. He was listed in the 2014 William E. Simon Graduate School of Business Administration Spring Teaching Honor Roll.
