 Research interests

One of my goals is to develop and apply new methods of paleoenvironmental reconstruction. My focus is the analysis of continental climate factors such as temperatures and isotopic compositions of fluids. Apart from fieldwork and operational support of the Stable Isotope Laboratory, I concentrate my efforts on methodological work on the geochemical proxy ‘clumped isotope’ and its temperature calibration for biogenic apatite.
