Areas of research:
- Development of detailed tephrostratigraphies in the Eastern Mediterranean region
- Advancing techniques for cryptotephra identification
- Abrupt climate change
- Reconstruction of Natural hazard events from sediment records
Current research projects:
I am currently involved in the ERC-funded STEEPclim project led by Dirk Sachse at the GFZ Potsdam, Germany. This project aims the reconstruction of consequences of past abrupt climate changes, in particular changes in aridity and precipitation at the end of the last ice age (15-10 kyrs ago) across the European continent, and its comparison with climate models. My role as cooperation partner is to identify identical (crypto)tephra layers in varved (annually laminated) lake sediments, e.g. in Lago Grande di Monticchio (southern Italy) and Steisslinger See (southern Germany), to facilitate dating and synchronisation of high-resolution palaeo-proxy data.
I graduated from the Justus-Liebig University of Giessen (Germany) in 1997 with a diploma degree in Geology specialising in the mineralogical fields of ‘Zircon Typology’ and ‘Geochemistry’. I went on to complete a PhD at the GeoForschungsZentrum (GFZ) and University of Potsdam (Germany) in 2000 on the development of a detailed tephrochronological framework in the central Mediterranean region. During my postdoctoral employments at the GFZ (2000-2005) and at the Institute for Geophysics at the University of Texas at Austin, USA (2006-2008), I set a further special focus on the reconstruction of Holocene palaeoclimate variability, human environmental impact and historical records of Tsunami, hurricane and extreme drought events recorded in Late Quaternary lake sediments from the Central and Southern Americas. During the following employment at the GFZ Potsdam (2011-2015, 2017) and at Senckenberg Frankfurt/Heidelberg University (2015-2017) I developed new and advanced methods in the detection of cryptotephra layers in annual laminated lake sediments (NE Germany, N Poland, Italy) and in a long high-resolution peat record in Greece. In December 2017, I joined the University of Portsmouth as Reader in Environmental Change.
