Main Focus

As lab manager of the stable isotope group of the Department of Archaeology she is committed to developing and applying novel stable isotope methodologies (such as compound specific isotope analyses of dD and 13C) in the study of the human past. In particular, Jana facilitates the use of isotope methodologies in the study of intra- and inter- societal differences in prehistoric and historical human diets, the development of detailed human stable isotope ecologies, and the development of new, detailed palaeoenvironmental proxies of immediate relevance to studies of past human responses to climatic and environmental change.  She is responsible for the maintenance and day-to-day running of state of the art Gasbench-irMS, TC/EA and EA irMS, GC-MSD and GC-c-irMS, as well as other equipment used in the preparation of archaeological samples for stable isotope analysis. Jana is also in charge of student and postdoctoral student training in the use of the equipment, and health and safety protocol, within the laboratory.

On-site Isotopic Records of Human-Environment Interaction

Curriculum Vitae

Jana received her Master in Geography at the Technical University Dresden, Germany in 2006, where she applied U/Pb dating of zircons from the Harz Mountains, Germany using Laser-ICP-MS. In 2009 she received her PhD from the University of Bern, Switzerland in palaeogeoecology. For her PhD she focused on landscape and climate reconstruction applying 10Be surface exposure dating in the Central Andes. As a visiting scientist at Brown University, USA, she focused on alkenone-paleotemperature determination and foraminifera determination for estimating past ocean productivity in the eastern equatorial Pacific. At the University of Bern she ran the stable isotope laboratory as well as the cosmogenic nuclide laboratory of the biogeochemistry and palaeoclimate research group of the Department of Geography. She has supervised BSc, MSc and PhD students in lab work and research with the research focus on climate and landscape change since the last ice age in Eurasia applying biomarker and stable isotope analyses (compound specific dD, 13C), as well as 10Be surface exposure dating.
