Bakgrunn og aktiviteter
Jeg forsker på numeriske metoder for bruk innen geovitenskap (reservoarsimulering, CO2 lagring, overflatevann, mm), men er generelt interessert i anvendt og beregningsorientert matematikk. Mye av tiden min brukes til å utvikle åpen kildekode.
Jobben min på NTNU går i hovedsak ut på å veilede master og doktorgradsstudenter. Ta gjerne kontakt dersom du ønsker veiledning eller ønsker annen form for faglig samarbeid.
