Research Overview

I am a 'geometric analyst' whose main research interests are questions related to curvature driven heat-type flows of hypersurfaces. I am interested in second order and higher order nonlinear evolution equations (and corresponding elliptic problems). Questions of interest include short- and long-time existence, formation of singularities (where the curvature becomes unbounded) and their classifications and extension of classical flow solutions beyond singularities using a 'surgery' procedure. Such analysis relies heavily on techniques from differential geometry, partial differential equations, functional analysis and topology.

Teaching Overview

I have taught many undergraduate subjects at three Australian universities over the last 15 or so years, to mathematics students and as service subjects to engineering, physics, computer science and IT students. This includes first year single variable calculus, second year multivariable calculus, linear algebra, differential equations and complex analysis. At third year level I have taught calculus of variations, geometry of curves and surfaces and numerical analysis. I maintain an interest in teaching and learning theory of partial differential equations and regularly offer related undergraduate student projects.
