About
I currently serve as Interim Chair and Associate Professor in the Department of Operations and Analytics in the Alvarez College of Business at The University of Texas at San Antonio. Previously, I was a faculty member in the Department of Applied Statistics and Operations Research at Bowling Green State University.
My research uses optimization under uncertainty and machine learning to improve decision-making in healthcare and infrastructure services. In healthcare, I collaborate with clinicians on models for radiotherapy, perioperative management, treatment evaluation, quality control, and workforce scheduling. In infrastructure services, I develop analytics and optimization models to support sustainable, equitable, and resilient service delivery. I am an active member of INFORMS and POMS, and serve on the editorial board of Scientific Reports.
