Patrick Roberts is Group Leader of the Stable Isotope Research Group at the Department of Archaeology, Max Planck Institute for the Science of Human History. He is committed to applying stable isotope methods within multidisciplinary research programmes that are focused on human palaeoclimates, palaeoenvironments, palaeodiets and palaeomobility. Patrick has a number of international peer-reviewed publications that use stable isotope analysis in a variety of archaeological research contexts: from reconstructing palaeoenvironmental conditions in East and South Africa, South Asia, and Saudi Arabia associated with human habitation of these regions during the Pleistocene to dietary complexities in 18th and 19th-century historical populations. Patrick’s other interests include early human cognition, hominin dispersals, human relationships with tropical forests, megafaunal extinctions, and the interaction between climatic and social changes in prehistory and history. Patrick has recently published a new book titled, "Tropical Forests in Prehistory, History, and Modernity," which includes a chapter on tropical urbanism.
