I am a senior lecturer at Macquarie University. My research interests lie in applied mathematics at the intersection of asymptotic analysis of multiscale dynamical systems, nonlinear partial differential equations, and functional analysis. Currently, I am interested in mathematical climate models which involve heat convection, phase separation and solidification in sea ice. I am investigating the network formation and evolution of brine inclusions in sea ice. In this model, the salt entropy relative to the liquid water molar function provides a transparent mechanism for salt rejection under ice formation.

I also study the effective thermal conduction in sea ice in the presence of fluid flow, as an important example of an advection-diffusion process in the polar marine environment. Using new Stieltjes integral representations for the effective diffusivity in turbulent transport, we have obtained a series of rigorous bounds on the effective conductivity.
