Overall, I'm interested in the applications of mathematics to medicine and physiology, and to biology in general. In particular, the mathematical methods I tend to use are dynamical systems, differential equations, and numerical methods. Of greatest interest to me are spatial and temporal pattern formation, oscillations, nonlinear waves, and excitable systems.

For most of my career the principal focus of my research has been the dynamics of intracellular calcium oscillations and waves. Why do they occur? How do they occur? What are they doing? I'm glad you asked ...
