About

Andrew Daw

Hello! I am an assistant professor in the Data Sciences and Operations department within the Marshall School of Business at the University of Southern California. Prior to joining USC Marshall, I completed my PhD at the School of Operations Research and Information Engineering at Cornell University, where I was advised by Jamol Pender and supported through a National Science Foundation Graduate Research Fellowship.

What's my research about?

My research focus is in operations research and operations management, most often in service operations. I am particularly interested in stochastic models shaped by interactions, in which the activity in one process can drive future activity within itself and reciprocally in other inter-related processes. These interactions can affect service systems on the arrival side, such as I've recently studied in the context of bursts of autonomous vehicle support requests, and on the service side, which is the focus of our recent work on co-produced service in customer contact centers. Because these are stochastic models, the conceptual forebearer of the interaction models is the self-exciting Hawkes process, which has natural and relevant connections to virality, contagion, preferential attachment, and rich-get-richer models. My goal is to use these models to better understand interactive operations both analytically and empirically, and to use these insights for informed operational decisions.

What's operations management about?

I like to tell my classes that in operations management we are both poets and quants. I see operations management as a mathematical poetry, in which we describe scenarios and problems with models and data. Like the best poems can, our descriptions are meant to give us new perspectives on the systems and processes that we study, and these perspectives are likewise meant to guide and shape our decisions. We have a responsibility to remember, though, that decisions on processes often become policies, and only an exclusive few have the power to make policy.
