Bjorn von der Heyden completed his Ph.D. in geology at Stellenbosch University in 2013 and subsequently spent two years working as a geologist in the South African minerals for Exxaro Resources Ltd. After his exposure to the mining industry, he returned to academia appointed as a lecturer in Economic Geology. 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.
