For his BA in Archaeology, Jan Dekker studied at Leiden University, the Netherlands focusing on applying ZooMS to Mesolithic barbed points from Doggerland using minimally invasive sampling techniques. He continued his studies at Leiden with a Research Master of Science, during which he went on a one-year exchange to York University. The focus of his master thesis was applying MALDI-MSI on teeth in order to investigate spatial differences in the intensity of the bone protein osteocalcin as a potential stress marker. Now, he is a PhD in the ChemArch network, based at the University of York and the University of Copenhagen. His current research focuses on analysing the proteins preserved in charred foodcrusts as a way to study dietary changes during the Mesolithic to Neolithic transition.
