Paul Behrens is an Assistant Professor in Energy and Environmental Change at Leiden University. A physicist by training, Paul received his Masters in Physics and Astronomy from the University of Sheffield (UK) after conducting research at the Isaac Newton Group of Telescopes (Spain). His PhD is from the University of Auckland (New Zealand), where he developed remote sensing techniques for the harnessing of wind energy. Before joining Leiden University Paul worked at the Royal Society of New Zealand, providing expert scientific advice to the New Zealand Government on environmental sustainability and other topics. He has worked in industry, NGOs, and academia. His current work focuses on the environmental impact of human consumption, including energy, food, and water. Paul is passionate about science outreach and his recent research, published in the Proceedings of the National Academy of Sciences and Nature Energy, has appeared in The New York Times, the BBC, and Scientific American.
  
David Ehrhardt is an Assistant Professor in International Development at Leiden University. With a D.Phil in Development Studies from the University of Oxford, David subsequently worked as a post-doctoral Research Officer in Oxford's Department of International Development. In his current research, he uses qualitative and quantitative research methods to understand the efficacy and development of 'hybrid' governance in Nigeria as well as comparatively. In the past, his research has explored ethnic and religious conflict and cooperation; the development of political authority beyond the state; and the ways in which inequality and governance interact in the formation of group identities and violent conflict. At Leiden, David coordinates a BSc programme in governance, economics, and development.
  
Thijs Bosker is an Associate Professor in Environmental Science at Leiden University. He obtained a BSc and MSc in Plant Science at Wageningen University (the Netherlands), specializing in sustainable agriculture. Next, he worked for an NGO where he focused on reducing pesticide emissions to the environment. In 2005 he moved to Canada to complete a PhD in aquatic toxicology at the University of New Brunswick. He continued as a postdoctoral fellow at the Canadian Rivers Institute, became an Assistant Professor at the University of Connecticut (USA), before moving to Leiden University. In his current research he uses laboratory and field techniques to study impacts of contaminants on ecosystem health. He has worked on a variety of environmental issues, with a special focus on the combined impacts of contaminants and environmental stressors on reproduction and development of organisms. At Leiden University he coordinates the BSc programme Earth, Energy and Sustainability.
