Johanna R von Holdt, (PhD)
Dr Johanna von Holdt, a UCT postdoctoral research fellow specialising in various aspects of mine dust. As the UCT mine dust networking group co-ordinator, Dr von Holdt is perfectly placed to coordinate the GCRF Mine Dust and Health Network activities, play an active role in Network discussions and activities, and to subsequently help to implement research directives that result from the Network.
Her research career developed during her time at the Texas Transportation Institute (TTI) at Texas A&M University and at the Council for Scientific and Industrial Research (CSIR) in Pretoria where she was involved in several research studies on soils and materials for road construction. She also wrote and implemented the ISO17025 quality system in the Built Environment lab at the CSIR. Johanna built on her research experience by pursuing her postgraduate studies at the University of Cape Town and completed her MPhil in 2013 during which she shifted her focus to aeolian mechanisms, processes and impacts. She has developed several successful collaborations during her time at UCT, including providing expertise on the influence of soils and aeolian processes on spatial vegetative patterning as part of a research team based in Biosciences, lecturing on soils in Landscape Architecture, and facilitating the Honour’s field trip in Geology.

Professor Giles Wiggs
Prof Giles Wiggs is a desert geomorphologist at University of Oxford, UK, specialising in the physical processes controlling how dust is transported by the wind (aeolian sediment transport), including using modelling to determine the role of vegetation, moisture, topography and human activity in the mobilisation of dust. His projects span Africa, Central Asia, Middle East and Australia and he has led international research teams funded by the Natural Environment Research Council (UK), South African National Science Foundation, Medecins sans Frontieres and the British Council. He has made great effort to determine the relative importance of atmospheric and terrestrial controls on dust and the impact of dust on respiratory health. Prof Wiggs will bring considerable experience and expertise to the network on several research areas, including source identification, monitoring and measurement, practices of dust control and mitigation and impacts on community health.

Dr Matthew Baddock, (PhD)
Dr Matthew Baddock, of Loughborough University, UK, brings to the Network crucial expertise related to dust production and wind erosion problems from human alteration of landscapes, such as mines. He is using satellite imagery to identify sources of dust and dust plumes, which provides a means to determine downwind locations and populations most vulnerable to active sources of dust. Dr Baddock is an early career researcher who has been a lecturer at Loughborough University since 2014. His involvement with this Network will provide important opportunities for his career development and further strengthen ties between young researchers at southern African and UK universities.

Dr Mazimkhulu Zungu, (PhD)
Dr Mazimkhulu Zungu is a Public Health specialist and senior lecturer in the School of Health Systems and Public Health of the University of Pretoria. He currently also holds the post of Acting Director, National Institute of Occupational Health. He has a strong interest in occupational health of mineworkers, having previously been a Director in the Medical Bureau of Occupational Diseases and Assistant Compensation Commissioner in the office of the Compensation Commissioner for Occupational diseases. He has published extensively on the problem of TB as an occupational risk of health workers, for which work he provided input into technical reports for the World Health Organization. He has also contributed to technical reports focussing on TB in the mining industry for the World Bank, South African Development Community and the National Institute for Occupational Health. His current research will focus on TB in a silica-exposed workforce, an important and under-researched area. His work has supported advocacy for improving the occupational health of vulnerable workers in the mining and health sector through effective mitigation and control of occupational exposures. With his expertise, Dr Zungu will assist with designing strategic research directions related to silica exposure and the factors associated with silicosis and tuberculosis among miners.
