Niklas did his PhD at the University of York as part of Geoff Bailey's ERC Project DISPERSE, where he studied the mobility and subsistence strategies of coastal populations in the southern Red Sea. His research on the seasonal consumption of shellfish, which had led to the accumulation of over 3,000 shell middens on the Farasan Islands (Saudi Arabia), involved the analysis of oxygen isotope ratios to reconstruct past sea surface temperatures and to reveal seasons of mollusc collections.
This research led Niklas to move to Greece on a Marie Curie fellowship at the
Institute of Electronic Structure and Laser, where he led the
ACCELERATE Project. Within this project, he aimed to make the geochemical analysis of mollusc shells more efficient through the use of
Laser Induced Breakdown Spectroscopy (LIBS).
His research now involves shells from all over the world including the UK, Denmark, Spain, Italy, Croatia, Greece, Turkey, Malta, Tunisia, Libya, Saudi Arabia, Oman, Japan, the Philippines, Tasmania, New Zealand, the US, Canada, and Brazil, with shells from the modern period as well as over 30,000 years old.
