Dr Sharad Master is a researcher and lecturer based at the Economic Geology Research Institute in the School of Geosciences, University of the Witwatersrand, where he obtained the degrees of BSc (Honours) cum laude and Ph.D. In 1997/8 he was awarded a Harvard-South Africa Fellowship, and was a Visiting Scholar at Harvard University. He has also visited other institutions in Zimbabwe, the Netherlands, Belgium, France, Germany, USA, the UK, Morocco, Australia, Russia, China, India, Turkey and Iran. He has worked extensively on stratabound sediment-hosted copper deposits in Zimbabwe, the Central African Copperbelt (Zambia and Congo), and the Kalahari Copperbelt (Namibia and Botswana). He has published extensively on a wide range of research interests, which include the regional geology and metallogeny of Africa, meteorite impact structures, chemo­stratigraphy of Proterozoic carbonate rocks, Neoproterozoic glaciations, palaeo­seismites, palaeotsunamites, aeolianites, and the History of Science.

Dr Master was a co-leader of IGCP 363 (Palaeoproterozoic of Sub-Equatorial Africa), and has participated in all the meetings of IGCP 485 (The Neoproterozoic margins of the West African Craton). He is a member of the South African National Committee for IUGS and IGCP, and was a voting delegate at several International Geological Congresses. He has been on the editorial board of several earth science journals, and has been a reviewer for a number of international journals. He has also acted as a reviewer for scientific research proposals for the National Research Foundation (South Africa), the South African National Antarctic Program, and the National Science Foundation (USA). He is a member of the Geological Societies of Africa, South Africa, America and Zimbabwe, and the American Geophysical Union; and has participated in many meetings on African Geology, most recently the CAG24 Meeting in Addis Ababa, Ethiopia in January 2013, and the Roy Miller Symposium in Namibia (August, 2014). He has been on the organising committees of several international conferences. He was a Vice-Chair of the Organising Committee of CAG23 (Johannesburg 2011), and is on the Organising Committee of the 35th International Geological Congress (Cape Town, 2016).

Dr Master has extensive teaching experience, having lectured undergraduate and postgraduate courses in stratigraphic principles, South African geology, African geology and tectonics, surface processes, and mineral resources. He has also given short courses on Stratabound Sediment-hosted Copper Deposits in Johannesburg, Windhoek, Lusaka, Kitwe, Chingola, Perth, and at Rhodes University, Grahamstown (annually from 1992-2012). Prior to his academic career, which started in 1995, he spent 15 years in the copper mining industry in Zimbabwe, where he worked as a mine geologist, exploration geologist, and researcher; he has also been a consultant with the Environment and Remote Sensing Institute, Harare, Zimbabwe. He has consulted widely to industry in the fields of African regional geology and metallogeny, stratabound copper deposits, and natural hazard assessment in Africa. Over the past 10 years, Dr Master has worked in South Africa, Namibia, Botswana, Zimbabwe, Zambia, Democratic Republic of Congo, Mozambique, Swaziland, Lesotho, Malaysia, Singapore, Australia, USA, Norway, Morocco, Algeria, Mauritania, Mali, Tunisia, Jordan, Brazil, Ethiopia, India and Iran.
