Biography

My Ph.D. work in the Department of Geosciences, the Pennsylvania State University, USA (completed in 2004), concerned organic geochemistry of Early Cretaceous petroleum rocks from West African lacustrine basins. I investigated molecular and compound-specific C and H isotopic composition of bulk organic matter and individual biomarkers. Since my postdoctoral research at Yale University, USA (2004-2006), I have been involved in laboratory and field investigations of environmental and post-depositional processes that influence C and H isotopic composition of lipid biomarkers from terrestrial and aquatic plants. I was involved in field studies of modern tree leaves throughout climatic gradients in California and Hawaii, USA.

Starting in 2005, I have been leading a multiyear study that investigates isotopic composition of leaf wax biomarkers at an experimental set-up in Eastern Washington State, USA. This work has been carried out in collaboration with Mark Pagani at Yale University. As part of this collaboration, I have been investigating lacustrine and marine sedimentary records of hydrological conditions during the Holocene (the Yucatan Peninsula) and Paleocene-Eocene Thermal Maximum (the Arctic Ocean), respectively. In 2007, I started a new project in collaboration with colleagues from the UK, Germany, Italy, and Spain in order to conduct a long-term investigation of stable isotope composition of leaf wax biomarkers from higher plants in Western Europe.
