Om
Jeg har en mastergrad i produktutvikling og produksjon (2013) og en PhD i konstruksjonsmekanikk (2017) fra NTNU med tittelen "Numeriske studier av duktilt brudd i aluminiumslegeringer". Etter endt PhD var jeg ansatt som forsker i tidsperioden 2017 - 2023. I 2023 gikk jeg inn i stillingen som førsteamanuensis ved Institutt for konstruksjonsteknikk.
Mine forskningsområder er faststoffmekanikk, materialmodellering og numeriske beregninger. Forskningen omhandler i stor grad modellering av plastisk deformasjon og brudd i metaller basert på en kombinasjon av eksperimenter, teori og numerisk modellering og simulering. Mikromekanisk modellering står sentralt i forskningen. Målet er å øke forståelsen av mekanismene som forårsaker brudd i materialene og å forbedre eksisterende beregningsmodeller for brudd.
