Research interests

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 carried out 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.

Teaching interests

I have taught a number of courses at different levels, including cosmology, exoplanets, star formation and plasma astrophysics. I have also taught and tutored courses in programming and mathematics.
