Research Interests

My individual research efforts and interests based on this theme are threefold. 1) I use probabilistic, mathematical modeling and predictive analytic methods to develop tools capable of improving individualized risk prediction, informing more accurate medical and surgical decision-making processes, and developing data-driven, population-based screening and management strategies for common diseases. 2) I apply mathematical models to genomic and epigenomic data to improve our understanding of the fundamental biology of disease processes. This includes nonlinear and dynamical systems / chaotic modeling strategies for cancer, but it also includes integrating molecular and clinical data so that these types of analyses can be applied in a clinically-relevant fashion. 3) I use comparative effectiveness and econometric analysis strategies to study the costs and benefits of alternate management strategies in an effort to maintain high-quality patient care while optimizing the efficiency of healthcare delivery.
