I will be teaching the 1st-year introductory linear algebra (`vectors and matrices') during the first three weeks of the autumn and spring term. In addition, I will teach part of the astrophysics option (jointly with Dr Subu Mohanty). Course materials for both will be available on `blackboard'.


For the postgraduate lectures, the summary notes are a bit large for this page, so I have split them into separate parts: introduction (stars_intro.pdf) and parameters (parameters_condensed.pdf). More to follow. 

Research Interests

My research interest is to observe and understand stellar activity on the

Sun and Sun-like stars.


  • Stellar Surface Imaging
  • Solar precursors: T Tauri stars and pre-main-sequence stars (see `Stars & Origins' on our group web pages)
  • Solar and Stellar irradiance variability (see links in the solar section)
  • H-alpha galactic plane surveys and spectroscopic follow-up:
