Welcome to my homepage

I am a researcher working in the Astronomy Discipline of the School of Physical Sciences at the Open University. My research focuses on cool stars and exoplanet detection and characterisation.

  • Research

    My research interests focus on the study of stellar activity, using high resolution spectroscopy. I have used tomographic techniques to obtain some of the first indirect images of spots on G dwarf stars like the Sun, and the least massive M dwarf stars. I have also performed searches for molecules in close orbiting extrasolar planets and implemented the most precise radial velocity searches for planets at the bottom of the main sequence.

  • Other

    In my spare time I enjoy hillwalking, running and cycling. I also dabble in photography and sometimes even manage to play the piano competently.
