Arjan de Leeuw completed his PhD in palaeomagnetism and geochronology at Utrecht University in 2011. His thesis addressed the Miocene evolution of semi-isolated basins in Southeast Europe, which typically lack common biostratigraphic markers, hampering biostratigraphic correlation. Physical dating methods provided new chronological constraints, which improved insight into some widely varying themes including basin evolution, geodynamics, mollusc lineages, mammal migration and the impact of global climate on local systems.
Arjan joined CASP in 2011 and leads the Northwest Black Sea Sediment Delivery Project. His research addresses the stratigraphy, sedimentary systems and geodynamic evolution of the Paratethys area.
