Steffen is interested in ocean and sea-ice variability and predictability, and how these contribute to predictive skill in an Earth System Model on time scales from days to seasons.

Professional interests: 
  • Arctic Predictability
  • Polar–lower latitude linkages in weather and seasonal prediction
  • Ocean–sea-ice–atmosphere interactions
  • Sea ice modelling, observation and data assimilation
  • Natural variability and climate change
Career background: 

Ph.D., Max Planck Institute for Meteorology. Hamburg, Germany (2012). Thesis on “Initialization and predictability of Arctic sea ice in a global climate model”. PhD advisors J. Marotzke, D. Notz, and J. Jungclaus.

Diplom (M.Sc. equivalent) in Physics, University of Potsdam. Potsdam, Germany (2008). Final grade: 1.0 (“with distinction”). Specialization in climate science (S. Rahmstorf) and nonlinear dynamics ( J. Kurths). Thesis on "Destruction of Anderson Localization in nonlinear lattices" (supervised by A. Pikovsky).

Visiting student, University of Warwick. Coventry, UK (2003–2004)
