Professor Matthew Collins from the BioArch group at the University of York is interested in the development of a branch of archaeology which uses molecules to reveal our past - so called biomolecular archaeology. This uses interdisciplinary approaches for the recovery and interpretation of molecular signals from ancient materials, with in his case, a specific focus on proteins and their breakdown products. Matthew trained as a marine biologist and wanted to study marine fossils, but archaeological materials have become the main focus of his studies.
