The keynote speakers

Jonathan Williams

Max Planck Institute for Chemistry

Session: Atmospheric Science

Professor Jonathan Williams is leader of the group ORSUM (Organic Reactive Species Understanding and Measurement) in the Atmospheric Chemistry Department at the Max Planck Institute for Chemistry. The group develops and uses novel technologies and methods for the study of atmospheric organic trace gases. The subject of his research includes the sources, sinks, and chemistry of these species through field measurements. Williams has published many articles, studies, and reports on performed measurements of VOCs over tropical forests, boreal forests, the Indian, Atlantic and Southern oceans, urban environments, and the stratosphere. He has coordinated many national and international research projects, including the Organics over the Ocean Modifying Particles in both Hemispheres (OOMPH) project and the Guyana’s Atmosphere-Biosphere exchange and Radicals Intensive Experiment with a Learjet (GABRIEL) project. With Paul Crutzen, he wrote Perspectives on our planet in the Anthropocene (CSIRO 2013), which overviews about global impact on population, energy and food demands, climate, air and ocean pollutions, biodiversity and erosion, as responses to human-driven changes to the Earth’s system.

Susan Trumbore

Max Planck Institute for Biogeochemistry

Session: Geoscience

Professor Susan Trumbore is the director of the Biogeochemical Processes department at the Max Planck Institute for Biogeochemistry. Before that, she was Professor in the Department of Earth System Science at the University of California Irvine (1991-2010). In her research she applies the radiocarbon method to study the dynamics of carbon cycling in vegetation and soils and how they are influenced by human activity and climate change. She has authored and co-authored articles related to the content of organic carbon in soils and how land management and climate change influence the soil carbon storage capacity. She was elected to the US National Academy of Sciences in 2010 and since 2014, she is the editor-in-chief of the renowned journal ‘Global Biogeochemical Cycles’.

Mark Lawrence

Institute for Advanced Sustainability Studies

Session: Energy and Climate

Professor Mark Lawrence is a scientific director at the Institute for Advanced Sustainability Studies (IASS), Postdam, and an Honorary Professor at the University of Potsdam. At the IASS, he leads the research cluster Sustainable Interactions with the Atmosphere (SIWA), which focuses on the impacts and mitigation of short-lived climate-forcing pollutants (SLCP) such as ozone, black carbon, methane and HFCs, and on the potential impacts, uncertainties and risks of “climate engineering”, targeted intervention in the atmosphere’s chemical and physical processes as a means of reducing climate change. His primary research interests also include numerical modeling and forecasting of chemical weather and chemistry climate interactions in the troposphere. Lawrence is author or co-author of over 100 peer-reviewed publications on these topics. He became a contributing author of the IPCC's Fifths Assessment Report of Working Group III on the Mitigation of Climate Change in the chapter on Assessing Transformation Pathways. He coordinated the European Union FP7 Trans-disciplinary Assessment of Climate Engineering (EuTRACE) project, and is a member of various international committees, including the UNEP Atmospheric Brown Clouds (ABC), the International Global Atmospheric Chemistry project (IGAC), and the international Commission on Atmospheric Chemistry and Global Pollution (CACGP).

Dim Coumou

Potsdam Institute for Climate Impact Research

Session: Energy and Climate

Doctor Dim Coumou is a senior research scientist at the department of Earth System Analysis at the Postdam Institute for Climate Impact Research (PIK). He received a Ph.D. in Natural Sciences from ETH Zurich for his work on the development of efficient multiphase fluid flow transport schemes for hydrothermal system applications. He is the main developer of a new atmospheric model, Aeolus, which is part of POEM (Potsdam Earth System Model), to study extreme weather events associated with atmospheric circulation. His current research at PIK focuses on extreme weather events like droughts, heat waves and heavy rainfall events. Since early 2014 he is leading a junior research group which studies the link between jet stream dynamics and weather extremes and how rapid climate change in the Arctic might influence this.
