Dr Bjorn von der Heyden obtained his Ph.D. from Stellenbosch University in 2013 for his research focussed on characterising iron nanoparticles and sub-micron particles using synchrotron X-rays. He subsequently spent two years working as a geologist in the South African minerals industry for Exxaro Resources Ltd. where he gained excellent exposures and experiences at Arnot underground coal mine, Grootegeluk open cast coal mine, and the Mayoko iron ore exploration project in the Republic of Congo.
In 2015, he returned to academia appointed as a lecturer in Economic Geology at Stellenbosch University (SU). In this role, he places equal emphasis on generating and publishing exciting new science, and on providing high-quality education to the next generation of African earth scientists. His current research interests include better understanding the controls on hydrothermal classes of ore mineralisation (notably gold mineralisation), the applicability of synchrotron X-ray spectroscopy to ore geology research questions, and the across-disciplinary field of applied geometallurgy. His current research field sites include the Kirk Range in southern Malawi and the Barberton greenstone belt, and he is proud to have recently developed fluid-inclusion microthermometry capabilities, currently housed at the Department of Earth Sciences at Stellenbosch University. He was elected as a fellow of the Society of Economic Geologists in 2021.
