My research interests focus on the formation and evolution of interacting binary stars. In particular I use indirect imaging techniques to map the mass flow between the two stellar components in the binary. The main goal is to understand the physics controlling the dynamics of the accretion discs that surround the accreting compact stars. Such disc-flows can be found in a wide range of environments, they determine the secular evolution of such compact binary systems and permit us to study the compact remnants of stars whether white dwarfs, neutron stars or black holes.
Some more specific interests include accreting white dwarfs as supernova Type Ia progenitors, ultra-compact double white dwarf binaries, galactic plane surveys, multi-wavelength astrophysics, novel observational techniques, neutron stars and black holes in binaries. I am an observationally focused astronomer, exploiting the spectrum of facilities available to us including the Hubble Space Telescope, X-ray satellites such as XMM and SWIFT and a wide range of ground-based observatories.
