Bakgrunn

 

 

Emil har en doktorgrad i fysikk fra NTNU september 2019 med bakgrunn i transmisjonselektronmikroskopi av deformerte aluminiumslegeringer. Fra tidligere har Emil en mastergrad i fysikk, også fra NTNU, der han studerte epitaksielle tynnfilmer av LaFeO3 grodd på (111) orientert SrTiO3 substrat. Han er i dag ansatt som senioringeniør ved NORTEM laboratoriene på Insitutt for Fysikk der han arbeider med opplæring av brukere, drift og utvikling av infrastrukturen, metodeutvikling, og strategisk utvikling.
