Research
My research involves building and analyzing mathematical models for a variety
of biological systems. Particular applications I am currently studying
include biological and artificial neural networks and plankton ecosystems.
Although physically unrelated, the behaviour of the these systems is often
influenced by the same factors: the presence of nonlinearities and
time delays. The time delays represent the time it takes information to
propagate from one part of the system to another. The nonlinearity represents
the fact that in these systems a small change in the state can often result in
a large change in behaviour. Mathematically, my research involves
dynamical systems theory (e.g., stability, bifurcations, centre manifolds and
normal forms) and its extensions to delay differential equations and nonsmooth
systems.
A detailed description of my current research projects is also available.
