I am co-director of new Palaeolithic excavations at Rajagala Thenna, Eastern Province, Sri Lanka, and am engaged in a wide range of interdisciplinary studies of South Asian prehistory and global Palaeolithic archaeology investigating long term interactions between human behaviour and ecology.
The excavations at Rajagala Thenna are the first to examine Palaeolithic occupation in the dry zone and so will open up a new chapter in Sri Lanka's prehistory. The use of digital recording methods in the field combined with high resolution sampling protocols enable the application of diverse analytical methodologies to study the sites material culture, population history, chronology and environments. This research investigates how the occupation and behaviour in the dry zone differs from evidence from established studies of wet zone Pleistocene sites in Sri Lanka, how this fits into regional and inter-regional patterns of cultural evolution and modern human expansion, and how Pleistocene populations engaged with radically different ecological structures than span southern Asia.
My wider South Asian research focuses upon how hominin populations have engaged with patterns of palaeoenvironmental change in western South Asia, a critical boundary between the Saharo-Arabian desert belt to the west and the monsoonal, mosaic habitats of the Oriental biogeographic zone to the east. Archaeological approaches include excavation and survey of new Palaeolithic sites in Rajasthan and Gujarat, India, combined with revisiting and revising the results of previous studies in the region based on published archives and museum collections. This is complemented by new palaeoenvironmental survey and studies, prioritising humid landscape proxies in this arid region to better understand when the region was habitable to hominin populations.
I have ongoing interests in the study of rock art landscapes in southern India. This is focused upon changing patterns of landscape enculturation with the spread of agropastoralism into Kurnool District, Andhra Pradesh, a region of enduring occupation by hunting and gathering groups. The rich record of occupation, rock art production and creation of megaliths augments economic evidence for complex interactions between populations with distinct lifeways that highlights the region as a symbolic frontier.
Beyond South Asia, my research involves fieldwork in poorly known regions of the world, including coastal Kenya, Madagascar, Senegal and the Arabian penninsula, spanning the Iron Age to Lower Palaeolithic and the application of multidisciplinary methods, such as digital recording, GIS, geoarchaeology, and palaeoenvironmental studies.
