Faglige interesser

Mine faglige interesser er først om fremst innen faste stoffers fysikk/materialvitenskap. Jeg har de siste årene jobbet med termoelektriske materialer, med spesielt fokus på å benytte elektron energitaps-spektroskopi (EELS) og transmisjonselektronmikroskopi (TEM). Med denne kombinasjonen kan man undersøke elektronstruktur og bindinger på nanoskala, noe som er spesielt viktig innen moderne materialvitenskap hvor fokus er nettop på å kontrollere materialers egenskaper ved å endre deres struktur på nanonivå.
