Research: My group's research focuses on past and present marine environments and their relation to climate and climate change foremost over the last 130 000 years. This research further includes studying the interactions between land, sea, and atmosphere. Our main tools are marine sediments with their contents of different microorganisms combined with instrumental hydrographic time series and process-oriented modeling. Our research further addresses proxy calibration and validation both through experimental and field studies, i.e. improve the tools we use to reconstruct the past.
I find it especially intriguing to work in coastal settings, which are often affected by human impact, such as fjords, the Skagerrak and the Baltic Sea but also coastal upwelling areas around the world’s oceans. I lead several projects, financed from the Swedish research councils VR and Formas, the Crafoord Foundation, and Oscar & Lili Lamm Foundation.
I collaborate extensively with the Marine Centre in Simrishamn, where Hanö Bay is one important focus area.
I'm active within LINXS Environment and Climate theme and the strategic research environment BECC
All open PhD positions are advertised on Lund University's vacancy page
Teaching: Course coordinator for the Master Course Marine Geology and Environmental Change (GEON08) and I teach on several other courses and typically supervise 2-3 Bachelor and Master Students per year.
