Research InterestsMy research focuses on problems in healthcare and the mathematical tools to tackle them. Applications include policy problems such as determining the most cost-effective way to (a) identitify cases, (b) treat cases, or (c) prevent cases of a disease. Often this related to modeling the spread of infectious diseases. Mathematical tools for such problems include deterministic and stochastic optimization and optimal control. See the link below for an overview of the healthcare activities in the department. I am looking for graduate students and encourage those interested to apply to the graduate program. |
