Wolfgang Preiser

University of Stellenbosch

Wolfgang Preiser is Professor and Head of the Division of Medical Virology, Faculty of Medicine and Health Sciences, University of Stellenbosch / National Health Laboratory Service (NHLS) Tygerberg. He specialised as medical virologist in his hometown Frankfurt, Germany, and at University College London and received his second doctoral degree (Habilitation) in 2005 while working as consultant virologist in Frankfurt. He was member of the German group among the first globally to identify the novel coronavirus causing the SARS outbreak in 2003 and subsequently served as an advisor to WHO in China. His principal research interests cover three broad themes: improving and advancing diagnostic virology, with emphasis on, but not limited to, HIV infection and antiretroviral drug resistance; the epidemiology, diagnosis, and monitoring of opportunistic viral infections, esp. hepatitis B and cytomegalovirus, in immunocompromised patients; and emerging and potentially zoonotic viral diseases. The latter includes identifying hepatitis E virus as a significant health problem in South Africa and studying its epidemiological patterns, and performing research on different types of viruses in small mammals (rodents, shrews and bats) from Southern Africa. This work has identified several novel corona-, paramyxo- and astroviruses, most notably a beta-coronavirus closely related to the Middle East Respiratory Syndrome (MERS) coronavirus in South African bats, and a henipa-like virus in a South African shrew species.

Julie Silva

University at Buffalo (SUNY)

Julie A. Silva’s research and teaching specializations are Economic and Development Geography, with a regional expertise in Sub-Saharan Africa. Her central research theme focuses on poverty and inequality, while also examining the important linkages between global economic and environmental processes of change. Her broader scientific goal is to expand our existing knowledge of economic, social, and environmental processes that perpetuate poverty and lead to growing income and power disparities between people and between places. Her work offers important new insights for changing the development trajectory in less-studied, remote rural regions that are rapidly integrating into the cash economy and are on the front lines of climate change. As her research on the socio-economic drivers of poverty and inequality has evolved, she has increasingly sought opportunities to collaborate with international and US-based earth scientists interested in extreme weather, climate change, and land use/land cover change. Dr. Silva has published in a wide variety of multidisciplinary journals, including Nature Sustainability, PNAS, and Global Environmental Change. Her research has been supported by a variety of federal grants, including, as Principal Investigator (PI), a National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award and a NASA Equity and Environmental Justice Award.
