  • Seksjon for økologi og naturforvaltning

Forskning: Min forskning er sentrert rundt atferdsøkologi med hovedvekt på dagrovfugler og ugler. Jeg studerer samspillet mellom dyr og deres miljø, med fokus på næringsøkologi (byttedyrleveranser), hekking og hvordan menneskelig infrastruktur – som vindturbiner – påvirker atferden. Ved å ta i bruk teknologi som automatisk videoovervåking og romlig analyse (GPS), søker jeg å fremskaffe kunnskap som sikrer bedre beslutningsgrunnlag for vern av sårbare bestander i møte med miljøendringer. Se også mitt pågående prosjekt: Hubro-prosjektet (StoryMaps). For mer informasjon om min forskning, se ResearchGate.

Undervisning: Jeg underviser innen økologi, zoologi, atferdsøkologi og naturforvaltning. Min undervisningsfilosofi bygger på prinsippet om konstruktiv samstemthet (constructive alignment), hvor jeg vektlegger studentaktiv læring og feltarbeid der det er gjennomførbart. Jeg er emneansvarlig for ECOL100, NATF100, ZOOL210, NATF301 og NATF370, og bidrar som lærer i ZOOL250. For nærmere detaljer om mitt pedagogiske grunnsyn, se min pedagogiske portefølje.
