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.

Ansa is using multiple geochemical proxies to reconstruct the distribution of redox zones in South African marine basins during the Great Oxidation Event. He is interested in the relationship between oxygen availability and the primary mineralogy of iron-bearing minerals in BIF horizons.
Main supervisor: Nick Tosca. Co-supervisor: Stuart Robinson
Brooke is based at the University of Oxford, researching redox conditions and phosphorous cycling in the Mesoproterozoic Roper Group, Australia, using traditional petrography and modern micro-analytical techniques.

Jess is investigating the palaeoclimate associated with human occupation of the Kuruman Hills, Northern Cape, during the Late Pleistocene. She uses U-Th dating, trace element and stable isotope techniques on secondary carbonate deposits (tufas) to reconstruct the timing of their formation and the environment during their deposition.
Mcdonald is analysing carbon, oxygen and strontium stable isotopes in carbonate rocks from the Neoproterozoic Nama Group, to constrain changes in weathering during the emergence of skeletal life.
Aidan is mapping microbial ecosystems in the Nama Group, South Africa, and using high resolution geochemical analysis to decipher their formation mechanism and local redox environment.
Neo is exploring how REE patterns vary among marine shells from a range of phyla. His work will contribute to the development of a new environmental and ecological proxy that can be applied in deep time.
For her Honours project, Mapaseka investigated trace elements in carbonates from the Upper Nama Group to constrain local oxygen levels in the final stages of the Ediacaran.
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 was a Master’s student at the University of Oxford. She used experiments to understand iron and carbon cycling on early Mars.
