Biography

Ohad Perry is an associate professor in the OREM Department. Before joining °ÄÃÅÁùºÏ²ÊÔ¤²â in August 2022, he was a tenured associate professor in the Industrial Engineering and Management Sciences (IEMS) Department at Northwestern University, which he joined in August 2011. His undergraduate degree is in Mathematics and Statistics from Haifa University, and his M.S. and PhD degrees are from the Industrial Engineering and Operations Research (IEOR) Department at Columbia University. After completing his PhD in 2010, he spent a year and a half as a post-doctoral fellow in Centrum Wiskunde & Informatica (CWI) in Amsterdam, the Netherlands. His research interests center around applied probability, with applications to queueing theory, inventory and control of stochastic systems. More specifically, his work focuses on developing analytical techniques, involving stochastic analysis, stability theory and dynamical-systems’ control to design and optimize service systems, such as call centers, hospitals, matching markets and inventory systems.
