Research



As a researcher I am interested in climate change on various time scales. I have worked with U/Th dating and interpretation of stable isotopes in speleothems from the Alpine area, Northern Africa, the Arab Peninsula, and South Africa as climate archives for the Pleistocene epoch, focusing on the Last Interglacial.
I have also worked with peat as a climate archive, studying stable isotopes and plant macrofossils from Sphagnum sequences from northern Canada and Russia. During the past 10 years I have mainly been working with stable carbon and oxygen isotopes in tree rings from northern Canada, Russia, central Europe and Fennoscandia.

Currently I am mainly studying the influence of urban climate on tree growth and how this can affect long climate reconstructions through biases during the calibration period, and I am also interested in trees as potential indicators of environmental pollution in soil and groundwater.
