I have been doing archaeological fieldwork in Portugal since 1993.  My research interests focus on prehistoric human land-use and decision-making as part of a socio-natural process.  I use a multi-scale approach to understand how past humans, especially Neanderthals and Upper Paleolithic modern humans in Europe, interacted with their environment.

Currently, I am conducting a 3-year collaborative NSF-funded project titled, Inquiry into the Origins of Modern Human Distributions. The project brings together an international team to recover high-resolution archaeological, geological and paleoecological records from the excavation of Lapa do Picareiro, a cave in central Portugal. The project is designed to test whether or not differences in land use and diet allowed Neanderthals to survive in southwestern Europe longer than anywhere else. The ultimate goal is to determine why Neanderthals went extinct and were replaced by modern humans. Lapa do Picareiro is a unique site, with about 10m of sediments spanning 50,000 years. The sequence includes almost 2m of deposits dated between 30-42 ka cal BP, making it an ideal locale to track changes in paleoenvironments and human ecodynamics across the Middle-Upper Paleolithic transition.  We just finished the 18th season of work at the cave with previous funding by the Wenner-Gren Foundation for Anthropological Research, the Archaeological Institute of America, the National Geographic Society and the University of Louisville. During this project, we discovered an early Aurignacian level that shows modern humans arrived in the region several thousand years earlier than previously thought. The finds also demonstrate that modern humans dispersed rapidly across Europe from their arrival in Bulgaria 46,000 years ago to Portugal by about 40,000 years ago, or even earlier. This latest work will continue in 2021.

Also, I recently completed a collaborative NSF-funded project titled, Human responses to late Pleistocene environmental change in the coastal zone of Portuguese Estremadura, with Michael Benedetti of UNC-Wilmington.  This project was a geoarchaeological survey of the coastal region between the towns of São Pedro de Muel and Peniche, about 100 km north of Lisbon. This project discovered dozens of new Paleolithic sites, including Mira Nascente and Praia Rei Cortiço, and several important stratified sections that contain uplifted Pleistocene beaches, tidal flats, estuarine muds and freshwater peats. The two sites demonstrate Middle Paleolithic settlement in coastal wetlands, a previously undocumented landscape setting for Neanderthal habitation.  Praia Rei Cortiço is particularly important because it represents a rare glimpse of Last Interglacial environments in Iberia. We plan to return to Mira Nascente for additional investigation.

In addition to my work in Portugal, I recently began a projects in Mozambique and Sudan with colleagues from ICArEHB (www.icarehb.com). These are collaborative, multi-disciplinary efforts funded by the Fundação para Tecnologia e para Ciências (FCT) in Portugal. The goal of both projects is to investigate the Middle Stone Age archaeology of early modern humans. In Mozambique, we conducted archaeological survey in Niassa province near Lake Malawi (Niassa locally). The survey team discovered dozens of new open-air MSA sites in the Ncuala Valley and tested several rockshelters in the region. In 2015, we surveyed in Gaza Province near Massingir. We returned to Massingir in 2016 to test a new Later Stone Age site, Txina-txina. In 2017, we continued our work at Txina-txina and surveyed for other sites in Massingir. We then began a new survey in the Vilankulos region where we conducted a rescue excavation of an Iron Age shell midden with exposed human remains. In 2019, we surveyed along the Save River in Sofala province where we discovered an extensive Later Stone Age site, Zimuara. The site dates to 40,000 years ago, making it the oldest LSA site in Mozambique. We are planning to return in 2021.

In 2019, Prof. Matthieu Honegger of the Université de Neuchâtel (Switzerland) invited Prof. Nuno Bicho of the Universidade do Algarve (Portugal) and me to investigate a few Middle Stone Age localities in the Kerma region near the 3rd Cataract of the Nile River in Sudan. With FCT support, we will begin a three-year archaeological survey for MSA sites in the region starting in late 2021.

Since 2018, I am a Member of Commission 8, Upper Paleolithic of Eurasia, Union Internationale des Sciences Préhistoriques et Protohistoriques (UISPP).
