VLBA image of RS Oph

Radio image of the exploding star RS Ophiuchi

My research interests lie in the broad area of astrophysical gas dynamics mainly applied to circumstellar phenomena.

These include theoretical and observational studies of classical and recurrent nova explosions, supernovae and planetary nebulae.

I combine modelling with observation at wavelengths ranging from the radio to the X-ray.

Me in the Andes

Observing - In my work I use observatories around the world, including the Very Large Telescope in the Andes mountains in Chile, the orbiting Swift spacecraft, the Hubble Space Telescope, and the radio telescopes e-MERLIN and VLBI.
