  • Biographical Description

  • I am an associate professor in the Dept. of Physics and Astronomy. My research focuses on the study of circumstellar material surrounding stars, particularly massive stars, throughout the course of their lifetimes. I use the combined techniques of observational spectropolarimetry and three-dimensional numerical radiative transfer modelling to probe the geometrical configurations of gas and dust surrounding these stars. I have applied these techniques to newly formed protostars, interacting binary systems, evolved mass-losing variable stars, and supernova explosions. My aim is to trace the structure of circumstellar material and the ways it mediates between a star and its environment over the course of the star's life cycle.
