Overview

Amy Ward's research focuses on the approximation and control of stochastic systems, with applications to manufacturing and service systems. Much of her work has focused on the impact of customer impatience and abandonments on service system performance. Her research has been published in Mathematics of Operations Research, Journal of Applied Probability, and Queueing Systems. Prior to joining USC, she was an assistant professor in the Department of Industrial and Systems Engineering at Georgia Tech.
