Fields of work

I am a Postdoctoral researcher (VR International Postdoc funding) based at SMHI but I spend part of my time at Université Grenoble Alpes, France and at St Andrews University, UK.

The aim of my research project is to understand the processes involved at the ocean-ice interface of Thwaites glacier, West Antarctica. I am particularly interested in the interactions between basal roughness under the ice shelf and the melt/freezing processes induced by the ocean. The final goal is to reduce uncertainties in ice shelf modelling, particularly threatened by climate change.

I use a series of models, at different time and spatial scales: the continuum ice flow model Elmer/Ice, the discrete particle model HiDEM, the ocean models NEMO (basin-scale model) and Firedrake (crevasse-scale). I am part of the International Thwaites Glacier Collaboration (ITGC) in the DOMINOS team (

Past experience

I defended my PhD in Glaciology at Uppsala University in 2018: Modelling calving and sliding of Svalbard outlet glaciers – Spatio-temporal changes and interactions

Between 2018 and 2020, I worked for SMHI at the professional services department to provide hydrological methods and applications to diverse users.
