Research interests

My reseach is a combination of observational and theoretical astrophysics in areas including

  • Emission processes of radio pulsars, including pulse-to-pulse variability
  • Radio polarization, especially with the aim of finding out more about magnetosphere configurations
  • Gamma-ray production of pulsars
  • Spin-down rate variability of pulsars, including spin-down state changes and rotational glitches
