Job description

Min forskning fokuserer på å implementere innovasjoner i anvendt matematikk og utvikle nye måleteknikker for å bedre forstå sammenhengende strukturer som er relevante for koblingen mellom kryosfæren, atmosfæren og hydrosfæren. Nåværende prosjekter involverer feltstudier av fysiske snøprosesser, fluiddynamikk for anvendelser innen snøvitenskap, og utvikling av verktøy for ikke-lineære dynamiske systemer.
