I am broadly interested in mathematical biology as well as nonlinear dynamical systems with applications to other areas of science. I am particularly interested in understanding and overcoming the limits of current methodologies to capture spatial and temporal complexity in phenomena of scientific interest. I am currently active in the following research areas:

  • Reaction-Diffusion Systems: pattern formation, diffusion-driven (Turing) instabilities, spatiotemporal phenomena (including chaos and heterogeneity), RD systems on static and growing manifolds, with applications to developmental biology, population dynamics, and tissue engineering.

  • Spatial Population Dynamics: discrete patch and spatially continuous models, random and deterministic dispersal, synchronization of metapopulations, with applications to ecological and epidemiological metapopulation models.

  • Nonlinear Dynamical Systems: dissipative dynamics (attractors and absorbing sets), numerical bifurcation analysis, and stochastic differential equations.

In all of these areas I am interested both in the scientific field or application, as well as in the theoretical and computational tools used. I primarily approach problems from a dynamical systems point of view, and I am keen to see applications motivate new theory in this field. However, I am much more motivated by developing approaches to solve problems as they are, rather than trying to force problems into a particular shape in order to use a specific hammer. While I have used several tools in the past, I am more than happy to pick up new methodologies in order to address an interesting problem. I am also happy to pursue questions outside of my main research interests, as long as I am able to provide a useful perspective in addressing them. In short, I am problem-driven rather than technique-constrained.
