Geir Egil Dahle Øien
Om
Geir Egil Dahle Øien er professor ved Institutt for elektroniske systemer (IES) på Fakultet for informasjonsteknologi og elektroteknikk (IE) ved NTNU. Fra 20. februar 2023 til 31.12.2026 er han ansatt i 60 % stilling som senterleder ved SEED - Centre for Science and Engineering Education Development.
Øien ble professor ved NTNUs Institutt for teleteknikk (nå del av Institutt for elektroniske systemer) i mai 2001. Han tilhører faggruppen for signalbehandling. Han var instituttleder ved Institutt for teleteknikk 2002-2004, dekan ved NTNUs Fakultet for informasjonsteknologi, matematikk og elektroteknikk (IME) fra 1. august 2009 til 31. desember 2016, og dekan ved NTNUs Fakultet for informasjonsteknologi og elektroteknikk (IE) 1. januar 2017 - 31. juli 2019. Øien var prosjektleder for NTNUs sentrale utviklingsprosjekt Fremtidens teknologistudier (FTS) fra 1. august 2019 til 31. desember 2021.
SEED er et tverrfakultært NTNU-senter, p.t. med Fakultet for naturvitenskap som administrativt vertsfakultet. Senteret har eksistert siden 2016 og har fokus på operativ og strategisk støtte og rådgivning knyttet til utdanningsfaglig kompetanseutvikling, studieprogramutvikling, pedagogikk, realfags- og ingeniørdidaktikk, læring, undervisning og vurdering. Fra 2023 skal SEEDs mandat og kapasitet oppskaleres betydelig, som et ledd i å implementere anbefalingene fra NTNUs sentrale utviklingsprosjekt Fremtidens teknologistudier (FTS). Øiens tilsetting i senteret er en del av denne oppskaleringen.
