Jeg er utdannet sykepleier (Haukeland Sykepleierhøgskole, 1985) og statsviter (Universitetet i Bergen, 1993) og PhD (Universitetet i Oslo, 2014).

Min yrkesbakgrunn er variert, men er i stor grad knyttet til virksomhet innen helsefag i offentlig og privat sektor (sykepleier Haukeland Sykehus - akuttmottak og Sykehuset på Voss - intensiv, sykepleier off-shore, vitenskapelig assistent Universitetet i Bergen, spesialkonsulent Stavanger kommune og Rogaland fylkeskommune, daglig leder Infovital ASA, helse- og sosial sjef Evje og Hornnes kommune, arbeidende styreleder/prosjektutvikler Evjeklinikken AS, instituttleder Universitetet i Agder).

Ved Universitetet i Agder, som instituttleder, universitetslektor, førsteamanuensis og nå som professor, har jeg undervist innenfor en rekke emner på bachelor- og masternivå (varierende fra samfunnsmessig planarbeid, organisasjonsteori, helseinformatikk, folkehelse, til anatomi, statistikk og forskningsmetode).  Mine forskningsfoki har vært rettet mot fedmeforskning, særlig knyttet til pasientrapporterte subjektive utfallsmål (PROMS), men er nå rettet mer mot  samfunnsvitenskap, folkehelse og sexologi.
