Research interests:

Bio-physical interactions at multiple spatial scales using various approaches such as ground based measurements (eg ice coring, drilling, EM31), airborne systems (eg UAVs, helicopter EM) and satellite remote sensing (eg SAR).

Running projects:

I am currently a member of the HAVOC project: Ridges – Safe HAVens for ice-associated Flora and Fauna in a Seasonally ice-covered Arctic Ocean. This is a Norwegian contribution to the year-long drift expedition MOSAiC.
