Biography

I am interested in ice-ocean-atmosphere feedbacks and their influence on large-scale weather and climate.

I detect links between different parts of the climate system, unravel feedback chains, diagnose their theoretical underpinnings, assess the extent to which deterministic mechanisms give rise to predictability, and work out storylines that connect remote processes at high-latitudes with tangible impacts on mid- and lower-latitude climate. To make progress, I use a variety of observational products and statistical tools, complemented by models.

As a key link between ice, ocean and atmospheric variability, freshwater has formed an integral part of my recent research. I am particularly interested in the role freshwater plays in weather extremes and in its potential to trigger an abrupt climate change.

Projects

Currently, I am working on the projects CLASS ("Climate Linked Atlantic Sector Science") and CANARI ("Climate change in the Arctic - North Atlantic region and impacts on the UK"). These projects build on results that we obtained during the recent ACSIS project ("North Atlantic Climate System Integrated Study").

In my studies, I am closely collaborating with the SNAP-DRAGON and WISHBONE projects on the dynamics and climate impacts of the subpolar North Atlantic circulation. I am also an active member of the international OSNAP ("Overturning in the Subpolar North Atlantic Program") group, and I enjoy collaborating with the ASOF community on "Arctic-Subarctic Ocean Fluxes".

Before joining the National Oceanography Centre, I worked as a postdoc at GEOMAR - Helmholtz Centre for Ocean Research Kiel, where I investigated ocean-atmosphere interactions in the subpolar North Atlantic region and participated in wide, international ocean observing programmes. In addition, I contributed to large EU projects, including Blue Action, NACLIM, FixO3, SeaDataCloud, AtlantOS, and the German RACE project, which focused on North Atlantic climate variability or on managing ocean data.

I received my PhD from Woods Hole Oceanographic Institution and Massachusetts Institute of Technology in 2015. During my PhD, I assessed the dynamics of strong winds across Greenland's coast and their influence on the ice sheet, sea ice and ocean.
