Eg arbeider i teknisk avdeling på Geofysisk Institutt. Mine arbeidsoppgåver krinsar rundt førebuing, gjennomføring og etterarbeid i samband med toktverksemd ved Geofysisk Institutt.

Eg disputerte for doktorgraden 11. august 2017. I doktoravhanlinga mi studerte eg vertikale blandingsprosessar i Polhavet nord for Svalbard. Med eit redusert isdekke kan meir vind-energi nå ned i det øvre vasslaget. I tillegg til direkte blanding gjennom vind, kan dette føre til ei auke i treghetsbølgjer, som også kan forplante energien nedover i djupet, og auke varmeutvekslinga frå det relativt varme atlanterhavsvatnet.
