Research
My research involves building and analyzing mathematical models for
biological systems. My current works focusses on applications in neuroscience
from the single cell to the network level. Past work includes applications in
ecology and engineering. A major theme of my research is the influence of
nonlinearities and time delays on the model behaviour.
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.
