Professor Nikki Wagner

Dr Nikki Wagner is a Professor in the Geology Department at the University of Johannesburg, Johannesburg, South Africa. Her research areas include coal petrography, trace elements in coal, coal geology, carbon dioxide capture and storage, coal oxidation, underground coal gasification, coal conversion, coal ash, vitrinite reflectance for thermal maturity determination, and so on. She completed her Phd in 1998, and shortly thereafter worked for Sasol in their Coal to Syngas Research Group, where her interest in trace elements in coal developed. Dr Wagner worked for Sasol for 6 years, before joining the School of Chemical and Metallurgical Engineering at the University of the Witwatersrand, Johannesburg, where she ran the Coal Research group for 8 years before moving back into geology at the University of Johannesburg in 2014. She is an Professor. Dr Wagner has over 34 peer reviewed publications, supervises a number of MSc and Phd candidates at UJ and other tertiary intuitions, is an active peer reviewer for over 10 journals, is accredited in all 3 of the ICCP accreditation programs, and is the elected editor of the ICCP News, where she also serves on the Council. Dr Wagner specializes in organic petrology, and is able to provide an analytical service to industry, parastatals, and tertiary institutions on coal, carbon, shale gas, coal ash, and so on.
