Rosalie Tostevin
Rosalie has a PhD in Precambrian sedimentary geochemistry from UCL, and a Master’s degree in geology from the University of Cambridge. She worked as a postdoc at the University of Otago for six months and the University of Oxford for three years. She joined the University of Cape Town as a lecturer in 2019.
PhD Students
Brooke Johnson
Brooke is based at the University of Oxford, researching phosphorous cycling in the Mesoproterozoic Roper Group, Australia, using traditional petrography and modern micro-analytical techniques.
Master’s Students
Emma Rosier
Emma is based at the University of Oxford, using culturing techniques to assess the impact of low sulfate seawater on microbial metabolisms. Her research will help us understand how life responds to changes in seawater chemistry through time.
Honours Students
McDonald Mtonda
McDonald is using oxygen isotopes in quartz veins to investigate fluid movement and deformation in Neoproterozoic glacial deposits from Koegel Fontein.
Alumni
Matthew Brady
Matt was a Master’s student at the University of Oxford, and is now a PhD student at the University of Cambridge. He used experiments to constrain sedimentary phosphate cycling under ferruginous conditions.
Alice Ashpitel
Alice was a Master’s student at the University of Oxford. She used experiments to understand iron and carbon cycling on early Mars.
Honorary Members
Dora Tostevin
Sometimes assists in the field. Works hard under all conditions. Expert on sticks and squirrels.
