My research interests involve using mathematical modeling and stochastic optimization methods (primarily Markov modeling, Markov decision processes, and Monte Carlo simulation) to build models that simulate the natural course of disease. These models allow for estimation of outcomes under different screening and treatment policies in the absence of randomized controlled trials, and can be used to optimize screening and treatment decisions for patients with chronic diseases. My current projects include optimizing treatment and policy decisions for patients with type 2 diabetes, validating infrastructure decisions and scheduling for rural tele-cystoscopy clinics, and developing optimal treatment guidelines for small renal masses.
