Prof Dr. Markus Ammann is professor at ETH Zurich and head of the research group Surface Chemistry (Paul Scherrer Institute) that performs laboratory studies related to the chemistry, photochemistry and kinetics of atmospheric multiphase processes involving organic, halogen, nitrogen oxide and odd oxygen species on substrates relevant for aerosol particles, cirrus ice, ocean surface, soil surfaces, snow and sea ice. Understanding these processes is relevant for the assessment of the human impact on atmospheric composition, climate, human and ecosystem health. We use a combination of in-situ spectroscopy, flow tube and chamber techniques to cover scales from molecular level world of interfaces to the microstructure in aerosol particles and to the mesosopic medium of snow. We educate young scientists in laboratory atmospheric chemistry within the frame of the Institute of Atmospheric and Climate Sciences (IAC) at ETH Zürich (Department of Environmental Systems Sciences, D-USYS).
Alex Baker is a Reader in Marine and Atmospheric Chemistry at the School of Environmental Sciences, University of East Anglia, UK. He has a Ph.D. in Marine Chemistry from the University of Southampton and has been working on chemical exchange at the air-sea boundary for the last 20 years. A major theme of Alex’s research is the characterisation and quantification of the supply of important nutrients, such as nitrogen, phosphorus and iron from the atmosphere to the ocean. A significant part of that work involves investigation of the factors that control the solubility of aerosol iron and other trace metals, because solubility of trace metals is often closely related to bioavailability for marine organisms.
Donna E. Fennell is a Professor in the Department of Environmental Sciences at Rutgers University, New Brunswick, NJ, USA. She is an environmental engineer/microbiologist who received a PhD in Civil and Environmental Engineering from Cornell University, Ithaca, NY, USA. Her work seeks to understand and harness microbes to degrade or detoxify pollutants in terrestrial, aquatic and atmospheric environments. Her research in bioaerosols and bioremediation blends environmental engineering and molecular microbiology to elucidate, monitor and control complex microbial systems. Her current research is investigating airborne activity of bacteria to determine if these organisms consume aerial volatile compounds and have an impact on global cycling of contaminants.
Prof. Hartmut Herrmann is Professor of Atmospheric Chemistry at the University of Leipzig and Head of the Atmospheric Chemistry Department (ACD) at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig. Since 1986, he has been actively involved in research on atmospheric multiphase processes at the Universities of Goettingen, Hanover and Essen, Germany as well as the California Institute of Technology (CalTech) in Pasadena, U.S.A, and, effectively since 1998, at the University of Leipzig and the TROPOS Institute. Since 2015, he is a Concurrent Professor at Fudan University, Shanghai, China. His research intends to understand the tropospheric multiphase system up to the level of its predictability. Model development is strongly based on experimental work both in the laboratory and in the field. Lab work utilizes state-of-the-art physical and analytical chemistry methods to study gas phase, aqueous phase, organic phase, surface and multiphase phenomena. Field work uses advanced techniques to understand chemical processing and composition of tropospheric particles, clouds and rain in the complex interplay of all the compartments involved.
