Research

Current research
My PhD project focuses on last interglacial (Eemian, c. 130 000 – 115 000 BP) climate variability. A complete Eemian 9 m lacustrine sediment sequence from Finnish Lapland is analyzed as part of a multi-proxy project involving scientists from several different countries. I study down-core diatom and chironomid assemblage change to make quantitative and qualitative inferences of lake development, climate and environmental change during the Eemian. 
 
Research interests
My research interests are in climate- environment- and landscape history and change, and in lake sediments as recorders of these changes. I am interested in history and studying paleogeography and paleoclimatology is in fact studying the history of the landscape and environment we see around us. I grew up in a typical mid-Swedish landscape where remnants of earlier inhabitants back to the Stone Age are scattered and easily seen across the landscape. It has been natural to reflect on how the surrounding landscape was perceived by them and how it affected the development of the societies living in it. I have studied archaeology and Quaternary geology and worked on several projects together with archaeologists. The climate-, environmental- and landscape- changes I studied had thus been constrained to the present interglacial, the Holocene. But now I have gotten the opportunity to study the climate of the preceding interglacial and hope to contribute to a better understanding of the climate system of interglacial periods.

 

I have been and am presently working with diatoms, microscopic algae, found in lake sediments as indicators of environmental change, but will also include chironomids, larvae of non-biting midges, in my studies. Both can be used for qualitative and quantitative (transfer function) reconstructions of lake status variables (e.g. pH, temperature, water depth and nutrients) indirectly related to climate, but also for making reconstructions directly linked to climate such as mean July air temperature reconstructions.
