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
McDonald Mtonda
Mcdonald is working on trace element and isotopic data in carbonate rocks from the Neoproterozoic Nama Group, to constrain changes in weathering and redox during the emergence of skeletal life.
Honours Students
Mapaseka Mashego
Mapaseka is investigating rare earth element patterns in microbial carbonates from the Ediacaran Nama Group, to constrain local oxygen levels in microbial reef systems.
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.
