Juan is a malacologist whose main interests lie in the study of the fossil Mollusca (Miocene to Recent) of northern Chile, the deep water Mollusca of Northern Chile and intertidal Chilean Mollusca.  His research centres on studies of the taxonomy and biogeography of Chilean marine Mollusca as well as the distribution of modern landsnails in Chile.  For a selection of Juan’s publications, please refer to the publications page.


Raúl has conducted research along the Atlantic South American coast as well as the coastlines of northern Chile and Peru. His major interests centre on material properties, taphonomy and taxonomy of molluscs. For a selection of Raúl's publications, please refer to the publications page.


Alejandro has worked at a number of sites in central and the north central coast areas of Peru, including Armatambo and Rinconada in the Rimac Valley, Caral in the the Supe Valley, and the Quebrada Gramadal and Quebrada Las Zorras in the Huarmey region. Her archaeomalacological research focuses upon subsistence, gathering techniques, and ethnoarchaeological questions.


Alberto’s work is focussed on the south-central area of La Pampa in Argentina, and especially the Chenque I site.  His current research investigates aspects of the procurement, production, exchange and use of ornaments made from shell.  For a selection of Alberto’s publications, please refer to the publications page.


Carola works primarily on shell midden sites of the coast of the Atacama Desert in Chile. She in interested in the subsistence strategies of fisher and coastal societies, the palaeoecology of nearshore habitats, and the mechanics of shell fishhook production. For a selection of Carola’s publications, please refer to the publications page.


Sandra’s research is undertaken in Argentina in Chile centred on the southern-most portions of South America. She has particular interests in artefact production, molluscan taphonomy, gathering strategies and the reconstruction of palaeoenvironments and palaeoclimate. For a selection of Sandra’s publications, please refer to the publications page.


Marcela has worked on shell material from a variety of sites in Chile from the semi-arid coastal region of Los Vilos, Isla Mocha, and Western Patagonia. Her interests are diverse, covering hunter-gatherer subsistence strategies, the nature of coastal adaptations, biogeography, taphonomy, the archaeology of shell mounds, and shell artefact production technologies. For a selection of Marcela's publications, please refer to the publications page and for anyone who would like to publish online, Marcela directs you to her site A pdf version of Marcela's thesis can also be found on the publications page.


Sergio is a palaeontologist, focusing on molluscs, who frequently works with archaeologists. His primary interests focus on taxonomy, taphonomy and changes in mollusc distributions. A selection of Sergio's publications may be found on the publications page.


Based at the Laboratorio de Zooarqueología y Tafonomía de Zonas Áridas at the Universidad Nacional de Córdoba, Patricia focuses her research on the environmentally-distinctive Patagonian region of Argentina. Patricia's major interest focus on reconstructing past subsistence practices, shell midden taphonomy, schlerochronology and shellfish gathering strategies.


Mark’s focus is assessing the nutritional contributions of shellfish.  He has worked in the Northern Great Basin in the US and has investigated a number of shell middens along the Snake River in Idaho as well as midden sites in the northern Amazon (Guyana).
