Epstein ISE Department Seminar

Speaker: S. Ayca Erdogan, PhD, Visiting Assistant Professor, Daniel J. Epstein Department of Industrial and Systems Engineering, University of Southern California

Talk Title: "Data-Driven Disease Modeling and Health-Care Operations Management "

Abstract: This talk will include data-driven modeling approaches to guide decisions related to health care operations management and public health. I will first present our micro-simulation model which was used to provide input for the recently announced guidelines of US Preventative Services Task Force on lung cancer screening. I will describe our model that simulates progression of lung cancer in the absence and in the presence of screening considering individual heterogeneity, and the data sources used during model building, calibrating and validating phases. The model is used to predict the observed results of clinical studies and estimate long term effects of screening both in terms of mortality reduction and overdiagnosis which were not possible to estimate reliably from previous screening trials due to ethical concerns and limited period of follow-up.

In the second part of my talk, I will introduce variants of stochastic programming models for optimal scheduling of patient appointments with uncertainty in service durations and in patient demand caused by no-shows and dynamic arrivals of urgent requests. Unlike most scheduling models, our models do not rely on specific assumptions caused by service time distributions. I will discuss structural properties of the models and present optimum schedules under different demand and cost structures.

Biography: Ayca Erdogan is a visiting assistant professor at Daniel J. Epstein Department of Industrial and Systems Engineering at University of Southern California. Before coming to USC, she was a postdoctoral research fellow at Stanford University School of Medicine between 2011 and 2013. She received her PhD in Operations Research from North Carolina State University, and B.S. in Industrial Engineering from Istanbul Technical University, Turkey. Her main research area is decision making under uncertainty with an emphasis on problems related to health care. She is working on both operations management problems including optimal patient scheduling and on individual and population level medical decision making problems specifically related to cancer screening.
