Personal profile
Research overview
I am a geologist investigating the long-term evolution of planetary crusts and interiors, and how this impacts their past and present habitability. I employ a broad range of analytical techniques to investigate high- and low-temperature processes on different planetary bodies:
1) I use petrological, microstructural and isotopic measurements to constrain the age, magmatic emplacement and subsequent modification (shock metamorphism, low temperature alteration) of martian meteorites.
2) In my current Research Fellow role, I use Earth analogue materials to investigate water-rock reactions and alteration products in the subsurface oceans of Jupiter’s and Saturn’s Icy Moons.
3) I have also worked on the early Earth, specifically detrital chromite and zircon records, and igneous rocks from other known and unknown planetary bodies.
Teaching activity
I coordinate SEES' summer schools, including ES4801 Geology Field Camp in Scotland, a 5-week course in geological field techniques open to attendees globally. Please contact me at [email protected] for any queries relating to the Field Camp or SEES' summer programme.
