I am a PhD student working on the time-evolution of terrestrial exoplanetary atmospheres under the supervision of Professor Oliver Shorttle. My recent work has explored transient events such as volcanic eruptions and stellar flaring to determine the timescale over which these phenomena have a detectable impact on the state of planetary atmospheres.
Originally from Edinburgh, Callum studied at Durham University for a Master's degree in astronomy. He wrote his thesis on the irregular object 'Oumuamua - the first object of interstellar origin detected passing through our Solar System. Using a combination of orbital modelling and observational data, he sought to explain various anomalous properties of this unprecedented visitor, such as its shape, acceleration, composition, and trajectory. For his PhD in Astrophysics at the Cambridge Institute of Astronomy, he has joined the exoplanet research group, and aims to answer questions surrounding exoplanet composition, habitability, and the origin of life.
