At Univ, I am the tutorial fellow in Earth Sciences. As such, I teach a broad range of introductory topics to the first and second years within the College. In the department, I give lectures on mineralogy, mineral physics, planetary formation and the chemical, isotopic and physical evolution of the early solar system.


My research focuses on understanding the early evolution of the solar system and planetary bodies. I utilise a range of techniques to accomplish this task, including paleomagnetic, chemical, structural and textural measurements of ancient terrestrial and extraterrestrial samples. My previous research has constrained the mechanism by which asteroids generated magnetic fields, which provided a unique window into their thermal evolution over their active lifetimes. Moreover, I have used magnetic measurements to constrain the spatial origins of different meteorite groups within the solar system, which has provided constraints on the migration of both asteroid-sized bodies and the earliest millimetre-sized solids throughout the solar system.
