Biography

I studied Mathematics and Physics as an undergraduate at the University of Auckland, then completed an MSc in Physics at the University of Auckland and a PhD in Applied Mathematics at Cambridge University. I held postdoctoral research appointments at the University of California, Berkeley and at Caltech before returning to New Zealand to take up a position in the Mathematics Department at the University of Auckland.

Research | Current

My research is in the broad area of dynamical systems within applied mathematics. Dynamical systems is the study of the qualitative properties of mathematical systems (typically nonlinear differential equations) that change with time. My interests include bifurcation theory, especially global bifurcations and bifurcations with symmetry, and applications of dynamical systems theory to physics and biology. 

My recent work has mostly focused on applying dynamical systems ideas to mathematical models of systems with multiple time scales, i.e., to systems in which some processes occur much faster than others. The existence of multiple time scales is common in models arising from cell physiology; much of my recent work aims to explain the complex behaviour observed in models of intracellular calcium dynamics.

Teaching | Current

I also often teach MATHS 260: Differential Equations and MATHS 761: Dynamical Systems

Committees/Professional groups/Services

I am currently the incoming Vice-President for the New Zealand Mathematical Society and Vice-Chair of the Society for Industrial and Applied Mathematics Activity Group on Dynamical Systems. Within the University of Auckland I serve on the University Academic Staffing Committee and represent this committee on the Faculty of Arts Staffing Committee.
