Research & Scholarship
Work at the intersection of health operations management and clinical service-line leadership — discrete-event simulation, combinatorial optimization and applied econometrics, grounded in the operational realities of academic surgical programs.

Operating Room Scheduling Efficiency: A Simulation and Optimization Approach
PhD dissertation, Florida Atlantic University — in progress
A three-year census of 35,772 orthopaedic surgical cases at a multi-campus academic health system, used to characterize baseline OR performance, build and validate a discrete-event simulation of the suite, identify the empirical drivers of OR-day overtime, and evaluate a CP-SAT scheduling optimizer against both observed practice and a greedy heuristic.
Three findings carry the work: delay cascades are the dominant structural driver of overtime; the optimizer eliminated scheduled overtime on a representative week and cut simulated daily overtime hours by 77%; and the institution’s block-governance rules produce a governance paradox in which the surgeons who most justify two-room access generate the most overtime when that access is withdrawn.
Predictors of Fall Risk in Adults Aged 40–69: An Analysis of NHANES 2001–2002 and 2021–2023 Cycles
In progress
