Roberto Bertollini holds a degree in medicine and a postgraduate degree in pediatrics, as well as a Master in Public Health. He is Coordinator of the Evidence and Policy for Environment and Health unit at the WHO Department of Public Health and Environment in Geneva with the special task to develop the WHO global policy and response to the health impacts of climate change. He was previously technical Director at the WHO Regional Office for Europe, 2000-2007. His main professional interests concern the environmental influences on health, with special reference to the effects of emerging threats such as climate change as well as the use of epidemiology for public health policy development and evaluation of public health programmes and practices.
During the years he has been involved in the development and progress of the environmental health agenda in Europe and led the organization of major scientific and political events including Ministerial Conferences, such as the one on Environment and Health, held in Budapest in June 2004.

Madeleine Thomson is a Senior Research Scientist at the International Research Institute for Climate and Society (IRI), where she chairs the Africa Regional Programme, directs Impacts Research and supports the IRI-Pan American Health Organization-World Health Organization collaborating centre activities. Trained originally as a field entomologist, she has spent much of her career engaged in operational research in support of large-scale health interventions, mostly in Africa. Her research focuses on the development of new tools for improving climate-sensitive health interventions (e.g. risk mapping and early warning systems for malaria, onchocerciasis, kala azar, etc.). This work has expanded into airborne infections and she is currently developing a substantive programme for meningitis environmental risk assessment in anticipation of the new conjugate A vaccine. In recent years, she has become increasingly interested in improving institutional and human capacity for incorporating climate information into health planning. She has been involved in a number of national and international projects.

Dr. Rogers is President of the Health and Climate Foundation (HCF), an international non-governmental organization dedicated to finding solutions to climate related health problems and supporting partnerships between health and climate practitioners. Prior to founding HCF, Dr. Rogers held various appointments in government, the private sector and academia including Chief Executive of the UK Met Office; Vice President Science Applications International Corporation; Director of the Office of Weather and Air Quality at the US National Oceanic and Atmospheric Administration; Director of Physical Oceanography at Scripps Institution of Oceanography, and Associate Director of the California Space Institute, University of California, San Diego, USA.
Dr. Rogers has a Ph.D. from the University of Southampton and Bachelor of Science degree from the University of East Anglia, UK. He has published extensively in the fields of oceanography, meteorology, climate, environment and organizational development.

Dr. Judy Omumbo is an Associate Research Scientist at the International Research Institute for Climate and Society (IRI). Her scholarly work has been mainly on GIS-based mapping of malaria in East Africa using climate and empirical data. Her current work is on developing currucula for training of public health professionals in the use of climate information for the analysis of climate and health ineractions and improved decision-making in climate sensitive disease programmes. She is a graduate of Oxford University (PhD), Hebrew University, (MPH) and the University of Nairobi (DDS).

Samson Katikiti is a Technical Officer with the World Health Organization – Regional Office for Africa and working in the malaria control programme focussing mainly in East and Southern Africa. His work is on malaria surveillance and supporting countries in use of Geographical Information Systems and Environmental Information Systems in early warning and response to malaria epidemics. He works in collaboration with national malaria control programmes, national meteorological departments, World Meteorological Organization, Southern Africa Drought Monitoring Centre and International Research Institute for Climate and Society in supporting use of climatic data in malaria epidemics preparedness and response.

Environmental Policy and Sustainable Development Coordinator of the National Planning Department of Colombia. This Department is the institution in charge of coordinating the design of all public policies and approves the investment budget for sectoral institutions of the national level. During the last two years he has been leading, on behalf of the National Planning Department, the design of the National Policy for Climate Change of Colombia, the national study for economic impacts of climate change. He was also in charge of leading the national team for the design of the Air Quality Policy and the National Environmental Health Policy, already issued. He will be acting as the technical secretary of the National Technical and Intersectoral Commitee of Environmental Health of Colombia as the representative of the National Planning Department.

Glenn McGregor is a graduate of the University of Auckland (BSc and MSc – 1st Class) and the University of Canterbury (PhD) in New Zealand. Currently he is Professor of Physical Geography and Climatology and Director of the School of Geography, Geology and Environmental Science at the University of Auckland. Before joining the University of Auckland in late March 2008 he worked in Geography departments at King’s College London, University of Birmingham, Hong Kong Baptist University and the University of Papua New Guinea as well as holding a research fellowship in the Institute of Low Temperature Science at the University of Hokkaido, Japan. Glenn is Chief Editor of the Royal Meteorological Society’s International Journal of Climatology, the WMO Commission on Climatology’s Lead Expert on Climate and Health, an Executive Board member and President elect of the International Society of Biometeorology.
Research interests cover the links between climate and health, vulnerability to urban heat and the climate mechanisms underlying hydroclimatological variability and change at a variety of spatial and temporal scales. Glenn has been involved in a number of climate and health related projects including: (i) seasonal climate forecasting and health in the UK (UK Natural Environment Research Council), nature and trends of London’s urban heat island (Mayor of London/Greater London Authority) and (iii) experimental heat health watch warning systems for 5 European cities ( EU PHEWE Project), (iv) the development and testing of summer season health forecasting models (EU EuroHeat project) and (v) climate change impacts in New Zealand (NIWA, NZ).

Having just graduated from the University of Sussex with an honours degree in International Development, Ms. Ellie Hopkins is now working in the field of campaigning against climate change. She has been working for the Age of Stupid on the global release of the film (www.ageofstupid.net) and now work for their new campaign 10:10, due to launch during WCC-3.
She also work as the logistics manager for the UK Youth Climate Coalition, working to put on the UK's first 'Power Shift' event to educate and empower young people to be able to take action on climate change in their communities. Whilst studying she spent much of her time campaigning not only on environmental but on youth and social justice issues, and as such won several awards, including the National Union of Students 'Student Unionist of the Year' award for her commitment to, and success in campaigning, particularly around climate change.
