Biography:
- BSc Geology, Utrecht University, The Netherlands
- MSc Geology, Utrecht University, The Netherlands
- PhD University of Gothenburg, Sweden
Title "Precambrian crustal evolution of the Rehoboth Province, southern Africa"
- Post-Doctoral Fellow Stellenbosch University (August 2013)
Research interests:
Geochronology, Metamorphic petrology, PT modelling, Archaean Geology, Geology of southern Africa
Current Projects:
Understanding Archaean geodynamic processes by modelling metamorphism, Barberton and Swaziland (Funded by the NRF and Innovation Postdoctoral Fellowships 2014-2016).
This project aims to use metamorphic information from rocks of the Ancient Gneiss Complex (Swaziland), the Assegaai-De Kraalen and the Barberton Granitoid-Greenstone belts (South Africa) to constrain the geodynamic scenarios relevant to metamorphism in these rocks. This will include new results from a metamorphic study combined with geochronology on the volcano-sedimentary rocks of the Dwalile Supracrustal Suite of the Ancient Gneiss Complex. As well as combining this work with PT-time path information produced by earlier works within the region to fit the geodynamic scenarios together and determine the nature and especially rate of the processes involved.
