I am a field geologist interested in the sedimentology, evolution and provenance of large-scale sediment systems and their response to geodynamics and climate. I teach sedimentology and field geology at the University of Grenoble Alpes. Most of my research is multi-disciplinary and involves a team of excellent collaborators. It has focussed on the geology and sedimentary architecture of the Pannonian Basin, the Dacian Basin, the Carpathian Foreland Basin and the intra-montane basins of the Dinarides. I have a background in magnetostratigraphic and radio-isotopic dating.

Before coming to Grenoble, I obtained a PhD at the paleomagnetic laboratory of Utrecht University, the Netherlands (2005-2010) and worked as a field geologist at CASP in Cambridge for six years (2011-2017).

Current research :
At the moment, my research focusses on the Miocene to recent evolution of the Carpathians and their foreland basin as well as the adjacent NW Black Sea shelf. Together with the Tectonics, Relief and Basins research group at ISTerre, as well as an international team of collaborators, we reconstruct how the basin evolved over time. We evaluate how the sediment system responded to changing tectonic and climatic factors. Field observations form the backbone of the reconstructions. Age constraints are provided by magnetostratigraphy and radio-isotopic ages. Detailed sedimentary facies analyses are integrated with studies of ostracods, foraminifera, molluscs and mammal fossils to reconstruct changing paleo-environments. We study auto-cyclic as well as allo-cyclic behavior of the corresponding sediment systems. Heavy mineral assemblages, rock fragment compositions, mineral geochemistry and zircon geochronology are used to retrieve sediment provenance. Quantitative constraints on the physical processes that shaped the basin are obtained through numerical modelling. We make intensive use of GIS and 3D software such as MOVE. This integrated research aims to explore all facets of the evolution of the sediment system connecting it with Carpathian tectonics, evolution of the Paratethys and regional as well as global climate changes.

Don’t hesitate to contact me if you would be interested in an MSc research or internship.
