Much of my research can be broadly defined as the development of 'on-site' isotopic records of human-environment interaction from archaeological- and hominin-bearing sediments. Mainly, I am interested in paleoenvironmental proxies of immediate relevance to the archaeological record, and use biogeochemical methods, such as plant wax biomarker stable isotopes, to provide detailed insight into vegetation change, precipitation patterns, biodiversity, and other paleoclimatological and paleoecological conditions. However, while this research theme has been applied in archaeology and paleoanthropology, records often remain at some distance from archaeological sites of interest.<br><br>My current research falls into three overarching themes:<br>1) Reconstruction of Pleistocene climates and environments to look at the ways in which hominins responded physically, technologically, and culturally to differing ecological settings throughout Africa, Asia, and Europe.<br>2) Application of innovative field and laboratory methods to address how early <i>Homo </i>adaptations to climatic shifts and environmental reorganizations differed from that of other hominins.<br>3) Production of higher temporal and spatial resolution paleoecological datasets within multidimensional archaeological and paleoanthropological projects to understand biome- and intrabiome-scale ecological change and the influence on human origins.<br><br><b>Publications</b><br><br>2022.
