The Postgrad Reps are TSG’s link to MSc and PhD students in structural geology community. They offer ideas and initiatives that would make TSG attractive or supportive to postgrads, and help promoting TSG to postgrad audiences. As a day-to-day task, they are in charge of our media presence, managing this website and social media accounts (Twitter, LinkedIn & Facebook).

Christopher McMahon (since January 2020)

Christopher McMahon is a current PhD student at the University of Strathclyde my research focuses on the architecture of shallow fault systems and how geofluids move through these systems. This is particularly important for several emerging geoenergy industries (e.g. CCS, energy storage, geothermal energy, conventional/unconventional hydrocarbons and nuclear waste storage) to ensure effective and safe storage of geofluids in the subsurface.

After studying for a BSc Earth Science (Hons) at the University of Glasgow, he went on to complete a MSc Applied Geoscience (GeoEnergy) at the University of Edinburgh. In both cases he learned fundamental skills and gained experience in petrology, structural geology, hydrogeology, geochemistry, numerical modelling, experiment design and reservoir geology.

He has fieldwork experience across Scotland, particularly in the NW highlands (Scotland), Oban, Kerrera, Ardnamurchan and Arran. In June 2018 he led a 3 week long research expedition to Uganda to the western branch of the East African Rift System to gather structural data, collect rock samples for further analysis, conduct qualitative social research and further collaborations between research groups and partner institutions.

Phoebe Sleath (since January 2020)

Phoebe is an MScR student at Durham University studying the Prøven Igneous Complex in West Greenland and its emplacement and deformation within the Rinkian Fold Thrust Belt. She is currently producing a detailed GIS map of the area using data compiled while working in the Photogeological Lab at the Geological Survey of Denmark and Greenland in Copenhagen. Phoebe obtained her BSc from Durham University in 2019 with her mapping dissertation studying the Canisp Shear Zone at Achmelvich Bay in Assynt, NW Scotland. Other than geology she can often be found running up mountains, rock climbing and painting watercolours!

Rebecca Robertson (since January 2021)

Bex Robertson is a PhD student at Durham University working in active tectonics, geomechanics and geochemistry. Her project aims to refining understanding of reactions occurring on faults during earthquakes, with a focus on fluid-rock exchanges. Her work combines synthetic samples with natural fault gouge from the Alpine Fault, New Zealand.

Bex completed University of Aberdeen’s 5 year MGeol course in 2019, with projects covering topics in: remote aerial photogrammetry of seismic hazards; Raman spectroscopy on UHP-HT eclogites and blueschists from Syros, Greece; mapping complex structures of the Ord Window, Skye which marks the tail end of the Moine Thrust. She then worked with the Virtual Outcrop Group in Aberdeen over the course of 2020.
