2016 BSc Geology Honours, University of Johannesburg, South Africa.
2019 MSc Geology, University of Johannesburg, South Africa. Dissertation title: Origin of sheared continental peridotites: A combined thermobarometry, mantle redox and Sr-Nd-Ca isotope study of xenoliths from the 1.15 Ga Premier kimberlite, Kaapvaal craton. Supervisor: S. Tappe

My PhD project is part of the DERTS programme and is supervised by Thomas Stachel and Graham Pearson. I will study inclusions in diamonds from the Juina kimberlites (Brazil). One aim of this research project is to establish the proportion of superdeep (sub-lithospheric) to lithospheric diamonds for the Juina kimberlite field. I will also specifically search for rare/new mineral phases in superdeep Juina diamonds using Raman spectroscopy. A second part of my PhD project will focus on diamonds from the Fort a la Corne kimberlite field in Saskatchewan. One principal goal is to establish a formation age for these diamonds through Re-Os dating of sulfide inclusions.
