Christoph leads the international climate policy analysis within the Energy Systems Group of PIK. He works on the representation of climate policies in coupled macroeconomic and energy system models to evaluate climate change mitigation strategies. His research interests include

  • interrelationship of mid-term climate policies and long-term policy goals, including questions of carbon lock-in,
  • national energy and climate policies and targets, including nationally determined contributions (NDCs) and mid-century strategies (MCS),
  • broader sustainability impacts of mitigation pathways,
  • how to use mitigation scenarios to assess companies' transition risks.

He studied Physics and Political Science at the Universities of Tübingen and Córdoba, Argentina, and holds a PhD in economics of TU Berlin. After working as WBGU research analyst for Professors Rahmstorf and Schellnhuber for one year, he joined the Energy Systems group of Research Department III: Transformation Pathways in April 2011.
