Jag är intresserad av hur klimatet och olika havsmiljöer har varierat bakåt i tiden, främst under de senaste ~130 000 åren (MIS5 och fram till idag). Andra intresseområden är nutida förändringar i havsmiljön särskilt i relation till mänsklig påverkan och hur vi kan förbättra verktygen vi använder för att återskapa forna tiders havsmiljöer. För att studera forna tiders klimat så måste vi utnyttja olika slags miljöarkiv. Jag använder mig av marina sediment och ett slags mikrofossil som heter foraminiferer. Foraminiferer är encelliga organismer, ofta med ett skal av kalk, vilket gör att de bevaras i sedimenten. Genom att studera hur artsammansättningen men även hur olika ämnen/isotoper i foraminiferernas skal varierar kan man få en bild av forna tiders klimat och miljö. Jag är dessutom intresserad av deras ekologi, varför en del arter trivs i vissa miljöer och andra inte, av hur bildningen av deras skal går till. Jag använder mig också av hydrografiska serier av temperatur, salthalt, syre, näringsämnen samt mäter stabila syre- och kolisotoper i olika vattenmassor för att förstå hur dagens havsmiljöer fungerar.
Jag är kursansvarig för Masterkursen Maringeologi och havsmiljöförändringar (GEON08), dessutom undervisar jag på flertalet kurser och handleder 2-3 Bachelor och Master studenter per år.
Jag samarbetar i stor omfattning med Marint Centrum i Simrishamn, där Hanöbukten är et viktigt fokusområde.
