Om

Forskning

Mi forskning er fokusert rundt utvikling av elektronstrukturteori for molekyl og molekylære system. Tidlegare har eg primært fokusert på kostnadseffektive (med tanke på reknekraft) algoritmer og modeller innanfor coupled-cluster bølgefunksjoner, samt mange-nivå skildringer der ein bruker ulike teorinivå for ulike deler av det molekylære systemet. Noverande interesser er å utvikle bølgefunksjonsmodeller for molekylære system der talet på elektron ikkje er ein bevart storleik, som følge av likevekts eller ikkje-likevekts vekselverknad med omgjevnadane.

I eit prosjekt finansiert av Norges Forskningsråd utvikler eg ein modell for ein partikkel-brytande bølgefunksjon for molekyl, og med finansiering frå Senter for Grunnforskning som Young CAS Fellow 2022-2024 har eg utforska korleis dette kan knyttast til skildring av redoksprosesser.
