My research

I recently completed my PhD under the supervision of Jochem Marotzke, Johann Jungclaus and Thorsten Mauritsen at the IMPRS and University of Hamburg. In my thesis I investigate two aspects of the climate system that can disrupt our expectations of surface warming on Earth:

  • internal variability, with a focus on the 1998–2012 slowdown in surface warming, and
  • changes to Earth's climate sensitivity.

In my current position I am investigating causal connections between decadal climate signals and previous climate states or policy decisions.
