We will present the list of speakers with a short bio in alphabetical order to give you an overview about their individual field of scientific expertise.

Last update: Oct 26

Gerten, Dieter
Dieter Gerten is a trained geographer (diploma 1997) and freshwater ecologist (PhD 2001). Presently he holds a position as Coordinator for Earth Modelling and Head of the Working Group “Terrestrial Safe Operating Space” at the Potsdam Institute for Climate Impact Research (PIK) and is at the same time Professor for Global Change Climatology & Hydrology at the Geography Department of the Humboldt University of Berlin. He has long-standing experience in water, biosphere and climate change research with a current focus on planetary boundaries. His publications – including more than 120 peer-reviewed papers as well as several books – span a range of topics such as climate change impacts on freshwater resources, water–vegetation interactions, water and climate change in religions, as well as food and bioenergy production within planetary boundaries.
Rachold, Volker
Volker Rachold is the Head of the German Arctic Office at the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research (AWI), which serves as an information and cooperation platform between German stakeholders from science, politics and industry. Before moving to the German Arctic Office in 2017, he served as the Executive Secretary of the International Arctic Science Committee (IASC) in Stockholm and Potsdam since 2006.
Dr. Rachold graduated as a geochemist from Göttingen University, where he also obtained his Ph.D. in 1994. Since then he worked with the AWI. His research focused on land-ocean interactions in the Siberian Arctic and he led several land- and ship-based Russian-German expeditions.
Reese, Ronja
Ronja Reese is a trained mathematician (master in 2013) and climate physicist (PhD in 2018). Currently, she is a postdoc at the Potsdam Institute for Climate Impact Research in the working group on Ice Dynamics and in the Future Lab on Earth Resilience in the Anthropocene. She investigates ice dynamics in Antarctic and Greenland with a focus on sea-level projections, interactions between the ice sheet and the surrounding ocean, ice-shelf buttressing and ice sheet (in)stabilities.
Rockström, Johan
Johan Rockström is Director of the Potsdam Institute for Climate Impact Research and Professor in Earth System Science at the University of Potsdam. He is an internationally recognized scientist on global sustainability issues and led the development of the Planetary Boundaries framework for human development in the current era of rapid global change.

Professor Rockström is a leading scientist on global water resources, with more than 25 years experience in applied water research in tropical regions, and more than 150 research publications in fields ranging from applied land and water management to global sustainability. He is i.a. member of the European Commission expert group: Mission Board for Adaptation to Climate Change including Societal Transformation, Chair of the Earth Commission and is elected member of the German Academy of Sciences Leopoldina.
