Mitt fagområde er pollenanalyse og vegetasjonshistorie med bakgrunn i botanikk og bl.a. arkeologi. Jeg ønsker å bidra til økt forståelse for hvordan menneskelig aktivitet gjennom tid har endret vegetasjon, biodiversitet og landskap, og mine forskningsinteresser spenner over et bredt spekter.
Eksempler på forskningsfelt:
- Sammenhenger mellom dagens vegetasjon og pollendeposisjon for å kunne gjøre kvantitative rekonstruksjoner av vegetasjonen i tidligere tider
- Metodiske forhold som påvirker estimat av pollenproduksjon som brukes i rekonstruksjonsmodeller
- Landskapsrekonstruksjoner på ulike romlige skalaer
- Introduksjonen av jordbruket og utviklingen av kulturlandskap med innmark og utmark
- Forståelse av forhistorien for forvaltningen av naturmiljø
- Mat, matproduksjon og handel i forhistorisk tid og middelalder
Forskningen er basert på feltanalyser av dagens vegetasjon og pollenprøver fra vannsedimenter, myrer og arkeologiske kontekster. Jeg samarbeider bl.a. med arkeologer i forbindelse med forvaltnings- og forskningsprosjekt og er ansvarlig for Universitetsmuseets paleobotaniske materiale fra arkeologiske utgravninger, som kan brukes i forskning. Jeg har et bredt internasjonalt nettverk, spesielt innenfor bruken av landskapsrekonstruksjonsmodeller.
Jeg kan tilby MSc- og PhD-oppgaver innenfor forskningsfeltene mine.
Jeg formidler mitt fagområde og min forskning gjennom trykte og sosiale medier, foredrag og utstillinger ved Universitetsmuseet i Bergen.
Sammen med osteolog Anne Karin Hufthammer er jeg faglig ansvarlig for utstillingen "Pollen og bein" som nå står i Naturhistorie, Muséplassen 3.
Jeg var faglig ansvarlig for utstillingen Pollen - så lite - så stort som ble vist ved Naturhistorisk museum/Universitetsmuseet i Bergen fra 2008 til museet stengte for rehabilitering i 2013. Deler kan fortsatt sees som nettutstilling.
