8/12/2023 — This paper presents the development, validation, and implementation of a data-driven optimization model designed to dynamically plan the assignment of anesthesiologists across multiple hospital locations within a large multi-specialty healthcare system. We formulate the problem as a multi-stage robust mixed-integer program incorporating on-call flexibility to address demand uncertainty. The optimized dynamic staffing plan has been successfully implemented in the University of Pittsburgh Medical Center healthcare system, leading to estimated annual cost savings of 12\% compared to current practice, or about \$800,000 annually.

6/4/2023 — About 27% of diabetics also suffer from depression, and the presence of co-morbid depression could increase the cost of care for diabetes by up to 100%. Several randomized clinical trials have demonstrated that physical and mental health are more likely to improve for diabetes patients suffering from depression when regular treatment for depression is provided in a primary care setting (called Collaborative Care). An important operational lever in managing Collaborative Care is the allocation of the care manager's time to enrolled patients based on their requirements, which in turn influences the revenue, costs, and patient health outcomes. We present a mathematical modeling approach that determines the optimal allocation of care manager's time and quantifies the costs and benefits of Collaborative Care.

1/12/2023 — Physicians spend more than 5 hours a day working on Electronic Health Record (EHR) systems and more than an hour doing EHR tasks after the end of the workday. In this paper, we investigate how physicians' workflow decisions on when to perform EHR tasks affect: (1) total time on EHR and (2) time spent after work.
