He has been affiliated with the Wiener Lab since 1992 and was its Acting Director from 1995-1997 and Committee Chair from 2011-2013. He is an archaeological geologist who is best known for his continued research on the provenance of ancient white marbles used in the Mediterranean Basin. Pike’s systematic mapping and intensive sampling of the Classical –Roman quarry pits on Mount Pentelikon in Attica, Greece demonstrated that intraquarry geochemical and isotopic variation can be used to discriminate between individual quarry pits, allowing for increased scrutiny of Greek and Roman resource exploitation. Pike’s recent research also includes landscape reconstruction and the incorporation of field-based geochemical analysis at active archaeological sites, including the Ness of Brodgar in Orkney, Scotland.
