Research areas

Anna is a World-leading St Andrews Doctoral scholar, interested in the science of EXOPLANETS. She works with Professor Andrew Collier Cameron on the detection & characterization of low mass, long-period exoplanets. As a collaborator of HARPS-N Science Team, she explores the high-precision radial-velocity measurements with stellar activity characterisation to push the limits on planetary mass determination down towards the Earth-mass regime.
