Dr. Galit Yom-Tov (Senior Lecturer)

Industrial Engineering, Operations Research and Optimization


Galit Yom-Tov is a Lecturer at Technion's IE&M faculty. Previously, she was a postdoc fellow and an adjunct professor at Columbia University's IEOR department. She received her M.Sc. and Ph.D. from the Technion, and worked in industry as an Industrial Engineer and IT specialist. Her research focuses on service systems. Galit is studying how data obtained from various service systems (such as call-centers and hospitals) can teach us about customer and agent behavior in such systems, and how queueing models can help to understand the operational implications of such behavior. She aims to build new operational methods for these systems in a way that will balance service and financial goals.
Galit's focus is mainly on healthcare systems (like hospitals) where her research can help to allocate resources such as beds, nurses, and physicians, so that patients will receive adequate service while considering financial constraints.
