My research interests lie in the general area of biomathematics. In particular, I am currently developing particle-based numerical methods that are capable of incorporating complex particle interactions (such as red blood cell interaction) so as to properly simulate blood flow in biologically meaningful geometries.

The numerical method is also being used for simulations of flow in chemical reactors, as well as for traditional fluid flow applications including Drag and Lift Coefficient calculations for shear flow past objects.


In general, additional research areas are: Biomathematics, non-Newtonian fluid flow, reaction-diffusion equations, modeling and simulations; applications to blood flow, cardiac arrhythmias, chemically reacting media, brain biomechanics and industrial fluid flows.
