Siden 2013 har jeg jobbet med solenergi i SINTEF, tidligere har jeg vært ansatt ved ScanWafer, REC og NTNU, og tematikken har vært den samme. Jeg har vært spesielt opptatt av produksjon av og egenskaper hos materialet som brukes i over 90% av alle solceller, silisium, og et hovedtema har vært dislokasjoner, korngrenser og forurensninger.
I den senere tid har jeg også begynt å jobbe mer med hvordan solceller brukes, for eksempel temaer som BIPV og soldeling i landbruket.
