Biography

I am an Associate Professor in Applied Mathematics at the University of Auckland, New Zealand. I was awarded her PhD from the University of Cambridge in 2006, and moved to New Zealand after two years of post-docs in the USA. My background is in the area of applied dynamical systems, but my interests range from theoretical studies of differential equations to using applications of mathematics to understand animal behaviour and navigation. My research has resulted in several awards, including the New Zealand Mathematics Society Early Career Award for Mathematical Research (2011) and the University of Auckland’s Early Career Research Excellence Award (2013).

Research | Current

I have a wide range of interests in the area of dynamical systems theory and applications to control and biological systems. I have made contributions to the dynamical systems literature in the areas of: heteroclinic cycles and networks; time-delayed feedback control; delay-differential equations; coupled cell dynamics; noise-induced dynamics; bifurcation theory. I have also worked in mathematical ecology, specializing in models of animal navigation, and animal movement and models of behaviour.

Teaching | Current

I regularly make contributions to the following courses:

  • Maths 190
  • Maths 260
  • Maths 340
  • Maths 761
