Ulrich Pöschl is director at the Max Planck Institute for Chemistry and professor at the Johannes Gutenberg University (JGU) in Mainz, Germany (www.mpic.de/3784916/profile-poeschl). He studied chemistry at the Technical University of Graz and was postdoctoral researcher, group leader, and university lecturer at the Massachusetts Institute of Technology (MIT), Departments of Chemistry and of Earth, Atmospheric, and Planetary Sciences; the Max Planck Institute for Chemistry (MPIC), Atmospheric Chemistry and Biogeochemistry Departments; and the Technical University of Munich (TUM), Institute of Hydrochemistry. Among other internationally leading scientists, Pöschl worked with the Nobel laureates Paul Crutzen and Mario Molina. His current research and teaching are focused on the effects of multiphase processes, i.e., interactions between gases, liquids, and solids, in the Earth system, climate, life & health. He is engaged in numerous international scientific collaborations, has been honored with prestigious scientific awards, and is among the world’s most highly cited researchers (Web of Science; Google Scholar). Pöschl has advised and mentored numerous students and postdoctoral researchers, many of whom are now faculty members or senior researchers in scientific leadership positions around the world. In accordance with Pöschl’s open and equitable approach of scientific teaching and mentoring, his students, postdocs, and alumni successfully pursuing an academic career come from a wide range of ethnic and societal backgrounds (~50% international) with a fairly even gender balance (~50% female). Pöschl actively promotes open science, and he initiated the innovative and successful approach of interactive open access publishing with public peer review and online discussion (multi-stage open peer review) as established in the leading international scientific journal Atmospheric Chemistry and Physics (ACP, www.atmospheric-chemistry-and-physics.net) and the European Geosciences Union (EGU, www.egu.eu). Moreover, Pöschl initiated and co-chairs the global open access initiative OA2020 (oa2020.org). (Adapted from: https://www.mpic.de/3784916/profile-poeschl)

I aim to gain fundamental insights into physical processes, and to probabilistically quantify hazards and risk. My geomorphological work develops algorithms and novel methods, and typically DEMs provide the primary observational constraint. With the insurance industry, my work on catastrophes aims to better understand and quantify the perils. Interests include: • Dynamics and mechanics of ice flow • Catastrophe modelling (i.e., risk, hazard and GIS) • Pacific volcanoes and deep Earth processes

Axel Kleidon studied physics and meteorology at the University of Hamburg and Purdue University. He received his Ph.D. in 1998 in meteorology from the University of Hamburg. After his PostDoc at Stanford University he joined the faculty of the University of Maryland in 2001. Since 2006 he leads an independent research group at the Max-Planck-Institute for Biogeochemistry in Jena, Germany. In his research, he uses thermodynamics to quantify natural energy conversions within the Earth system and their limits, and applies this approach to understand atmosphere-biosphere interactions, Earth system responses to global change, and the natural limits of renewable energy.
