His research focusses on sustainable solutions of the climate problem and related environmental systems under partially deep uncertainty. Since 2011 he has been member of the Scientific Steering Committees of Hamburg’s successive Clusters of Excellence on Climate, CliSAP and CLICCS.

Hermann Held holds a doctoral degree in Physics from the University of Munich. He spent a Feodor Lynen Fellowship by the Alexander von Humboldt Foundation at the University of California, Berkeley. During this period, he decided to merge his interests in natural science and applied mathematics with his interest in sustainable solutions. From 1999 to 2010, he worked on the climate problem at the Potsdam Institute of Climate Impact Research (PIK) first as PostDoc, then as Junior Research Group Leader (funding by the VW Foundation), and finally as Department CoChair, together with Ottmar Edenhofer. During this time, he also developed his interest in Climate Economics as a central research field in view of sustainable solutions. 2005-2009 he acted as President of the European Geoscience Union’s Division ‘Energy, Resources, and the Environment’. As expert he participated in hearings on carbon capture and storage on the federal and the state (Brandenburg) level.
