Jorune's research focuses on ancient proteins preserved in mollusc shells and developing shell palaeoproteomics. Jorune is interested in shell proteins as potential source of taxonomic information which could be used for molecular barcoding in order to determine the biological origin of archaeological shell samples. This is particularly important for heavily worked and/or degraded artifacts, as for example archaeological shell ornaments. In particular, during her postdoc she aims to expand molecular dataset for Spondylus gaederopus, also known as the Mediterranean thorny oyster, which was one of the most widely used shells in Europe’s prehistory and accounts to a high number of prehistoric artifacts found in archaeological sites. This work may help for archaeologist to securely identify Spondylus shell, as the raw material used for crafting ornaments. She is also interested in understanding how proteins break down in shells over time and uses mass spectrometry approaches to study protein degradation patterns that occur within shell biominerals.
