I am a post-doc researcher in the Astronomy and Astrophysics group at the University of Warwick under the supervision of Pier-Emmanuel Tremblay.
My research primarily focuses on understanding the nature of convection, in particular convective overshoot, in white dwarf atmospheres using CO5BOLD - a 3D radiation-hydrodynamics code. Convective overshoot is a boundary effect which requires a multi-dimensional treatment to be properly characterised. It causes the mixing of material outside of the layers where convective instabilities live and this is significant for understanding the mass of material mixed by convection, a key parameter in calculations of the mass and composition of accreted material. I study this using passive scalar tracers in 3D simulations which allow us to quantify the macroscopic diffusive properties of the region beneath the convection zone.
