I am teaching on several courses on bachelor and master's level. 

My research is directed towards the Late Quaternary and the climate development during this dynamic period in the history of Earth. I work with diverse climatic archives, ranging from marine cores from the North Atlantic, ice-cores from Greenland to terrestrial peat and lacustrine deposits in Scandinavia, the Azores and Patagonia. Although close similarities are evident in the palaeoclimatic reconstructions obtained from terrestrial, marine and ice-core records from the Late Quaternary period, uncertainties exist as to the degree of synchroneity (or asynchroneity) between them, largely due to the limitations of the radio-carbon dating method (radiocarbon plateaux, reservoir effects) and the lack of suitable dating methods for the time period before ca 40 ka BP. Therefore, new approaches are required for geochronology models and correlation of sequences and events. One method that holds much promise of effecting more precise regional correlations is tephrochronology. Chronological control and the resultant ability to examine the degree of synchrony among records of different origin are critical for the understanding of climate and environmental variability.
