Kristian Seip
Bakgrunn og aktiviteter
Kristian Seip (1962) har vært professor ved Institutt for matematiske fag siden 1993. Han har vært instituttleder (1997 – 2001) og prodekan for utdanning ved Fakultet for informasjonsteknologi, matematikk og elektroteknikk (2006 – 2012). Han er medlem i analysegruppen. Seip er utdannet sivilingeniør og har en doktorgrad fra NTNU. Hans forskningsområder er for tiden operatorrelatert funksjonsteori og analytisk tallteori.
