Prof. Walter Leal

Professor Walter Leal is a Biologist by training. He obtained his PhD on environmental science at the University of Bradord, UK, a DSc on sustainable development at London Metropolitan University, UK and a DSc on climate change at Manchester Metropolitan University, UK. He also has the titles of Doctor of Technology, Doctor of Letters and Doctor of Philosophy. His main research interests are in the fields of sustainable development and climate change, also including aspects of climate change and health. Professor Leal holds the Chairs of Climate Change Management at the Hamburg University of Applied Sciences (Germany), and Environment and Technology at Manchester Metropolitan University (UK). He directs the newly-founded Director, Interdisciplinary Centre on Climate Change and Health https://www.haw-hamburg.de/en/ftz-nk/ieccch/.

He has extensive experience on climate change adaptation, especially in developing countries, and created in 2008 the „Climate Management Management Series“ with Springer, which is the leading peer-reviewed book series on climate change, which also pays a special emphasis to aspects of planetary health. The Series, to which he acts as the Editor, has produced to date a comprehensive body of publications on climate change, among which mention may be made to the Handbook of Climate Change Adaptation with 3 volumes and around 150 authors, and the Handbook of Climate Change Resilience with 4 volumes and over 200 authors. Professor Walter Leal is also founding editor (also in the year 2008) of the International Journal of Climate Change Strategies and Management, an open access journal which works on the nexus between climate change mitigation and adaptation, and health.

Dr. Revocatus Machunda

Professionally, Revocatus Machunda (PhD) is an Environmental Scientist. He has a background in Chemistry and Applied Microbiology. He has over 19 years experience working as an academic staff at higher Institution of learning. Since 2011 he has been training and supervising graduate students and mentoring junior researchers. His areas of interest lie in the fields of Environmental chemistry, Toxicology, degradation of materials and Instrumentation and analytical chemistry. His current research is in the areas of water purification (the chemistry and microbial aspects), renewable energy in the form of Biogas and Sanitation (Mapping of Sanitation facilities, developing shit flow diagrams to that end and resource recovery from fecal sludge). He has over years worked to characterize biomasses for various applications including energy, activated carbons and catalysis.  He is also working on value addition to waste materials for various applications especially plant biomasses such as sisal; biomass derived activated carbons among others. He has worked on quantifying the environmental impacts of pesticides and other geogenic chemicals to the health of workers in specific farms and environment. He has received several grants funded by EU, DFID, COSTECH and DANIDA. He has also worked on quantification and profiling of sanitation workers. He has published over 82 journal papers, book chapters and has two patents on defluoridation technology and Biogas burner manifold.

Dr. Sam Myers

Sam Myers is a Principal Research Scientist at the Harvard School of Public Health and is the founding Director of the Planetary Health Alliance (www.planetaryhealthalliance.org).

Sam’s research explores the human health impacts of global environmental change. His projects currently include exploring the human nutritional consequences of rising concentrations of CO2 in the atmosphere, falling populations of pollinating insects, and changes in global fisheries in response to ocean warming. He is interested in policy interventions to improve human health while stabilizing Earth’s natural systems. As the Director of the Planetary Health Alliance, Sam oversees a multi-institutional effort (over 320 organizations in over 60 countries) focused on understanding and quantifying the human health impacts of global environmental change and translating that understanding into action globally. For his research, Dr. Myers was the inaugural recipient of the Arrell Global Food Innovation Award in 2018 and Prince Albert II of Monaco prize for research at the interface of health and environment in 2015. He is the co-editor with Howard Frumkin of Planetary Health: Protecting Nature to Protect Ourselves published in August 2020.

Prof. Dr. Wolfgang Preiser

Wolfgang Preiser studied medicine and then specialised in medical virology in Germany and the U.K. Since 2005 he has been Head of the Division of Medical Virology in Tygerberg, South Africa. This combines a large routine diagnostic laboratory, part of the South African National Health Laboratory Service (NHLS), with an academic training and research laboratory, part of the University of Stellenbosch. Access to numerous samples and the ability to employ state-of-the-art methods enables him to address scientific questions of relevance to sub-Saharan Africa.

His research aims to close gaps in clinical and diagnostic virology, focusing on three areas: (i) improving laboratory diagnosis and monitoring of HIV patients whilst addressing issues such as antiretroviral drug resistance; (ii) the epidemiology and management of opportunistic viral infections and conditions; and (iii) the identification and characterisation of potentially emerging zoonotic viruses in their wildlife reservoirs and in the human population.

The Virology Tygerberg team collaborate on numerous projects, including CLIMADE Africa https://climade.health/africa. This is an African consortium formed to generate knowledge, develop locally appropriate tools and inform public health action for early warning and timely/targeted responses to pathogens amplified by climate change. A key objective is to fill critical knowledge gaps and blind spots of disease transmission predicted to pose increased threats in the future.

Strengthening virological research and diagnostic capacity in Africa through education and training is of paramount importance to Preiser. He was Speaker for Africa’s first-ever international research training group 'HIV/AIDS and Associated Infectious Diseases in Southern Africa', providing structured PhD training for 12 candidates in Cape Town and 12 at the partner university in Würzburg, Germany. Other activities related to scientific training include collaborating partners in Tanzania, Botswana and Mozambique.
