Paul Nex is Associate Professor of Economic Geology at the University of the Witwatersrand. He graduated in 1991 from Oxford Polytechnic with a BSc. (Hons.) in Earth Sciences. He obtained his PhD from University College Cork (Ireland) in 1997 after research on uranium mineralization in granitic sheets in the Central Zone of the Damara Orogen, Namibia. After two years working in the petroleum industry as an MWD engineer he came out to South Africa to undertake post-doctoral research with Grant Cawthorn on the Bushveld Complex. From 2003-2007 Paul was a research fellow at the School of Geosciences undertaking research on the Platreef in collaboration with Anglo Platinum. For the last 7 years, until the beginning of this year, Paul was Senior Geologist at Umbono Financial Services, responsible for exploration oversight, targeting and evaluation of a wide range of mineral deposits, particularly critical metals and rare-earth elements. His main research interests are critical metal deposits, post-collisional Proterozoic mineralization with a focus on granitic pegmatites and also mineralization processes within the Bushveld Complex.
