PhD Project

My research focuses on the long-term stability behavior and potential critical thresholds—so-called 'tipping points'—of the Antarctic ice sheet under the scope of future global warming. In particular, I investigate how the stability of the Antarctic ice sheet is affected by the influence of interacting tipping elements in the global climate system, such as the Greenland ice sheet or the Atlantic meridional overturning circulation. The aim of my PhD project is to assess the likelihood that a tipping of the Greenland ice sheet influences the tipping potential of the Antarctic ice sheet. Using numerical ice sheet modelling, I want to answer the question, how such a tipping cascade impacts future sea-level contributions from Antarctica.

My work is funded by the Leibniz Association project DominoES – Domino Effects in the Earth System: Can Antarctica tip climate policy?, a joint project by the Potsdam Institute for Climate Impact Research and the Leibniz Institute for the Social Sciences, and the EU's Horizon-2020 project TiPACCs – Tipping Points in Antarctic Climate Components.

Research Interests

  • Ice sheet / ice shelf modelling (co-development of PISM)
  • Antarctic ice sheet stability and future sea-level change
  • Hysteresis behavior and tipping points of the Antarctic ice sheet
  • Climate and socio-economic tipping interactions (DominoES)
  • Earth system resilience (ERAlab)
