Henrik Koch
Om
Henrik Koch (1964) er professor i teoretisk kjemi. Han har master- og doktorgrad fra Aarhus Universitet i Danmark, med professor emeritus Poul Jørgensen som veileder.
Forskningsinteresser
Hans forskningsaktiviteter fokuserer på utvikling og anvendelse av nøyaktige elektronstruktur-metoder for molekyler generelt, og spesifikt for molekyler med sterk kobling til optiske og plasmoniske kavitet. Programvareplattformen er programmet eT (et program for elektronstruktur), som finnes fritt tilgjengelig på etprogram.org.
Nåværende stilling
- Professor ved Institutt for kjemi ved NTNU i Trondheim (Januar 2022 - )
