I am currently a Lecturer in the Department of Biological and Biomedical Sciences, School of Health & Behavioral Sciences, Bryant University and former Postdoctoral Research Fellow in Palaeoenvironmental Biomarkers in the Department of Archaeology. My research involves the use of stable carbon and hydrogen isotopes from archaeological sediments to answer questions concerning the relationships between environmental processes, cultural change, and human evolution.
My research lies at the intersection of paleoanthropology, paleoecology, and geochemistry and combines traditional archaeological field methods with area-defining laboratory techniques. A lot of my work uses different gas chromatographs and mass spectrometers, such as compound specific isotope ratio mass spectrometry, to try and understand what happened climatically and ecologically in the past, and what, if any, was the human response. I have had the privilege of travelling and doing research in the Bahamas, across Canada and the United States, China, South Africa, Spain, Tanzania, and Zimbabwe, and working in archaeological context ranging from 2 million years ago in eastern Africa to 2000 years ago during the Han Dynasty in China. I am always willing to discuss multi-proxy approaches to climactic and environmental reconstructions directly at new archeological sites.
Beyond my research interests, I try and invest in capacity building through cross-disciplinary training and granting greater access to scientific information. Much of this work has included strengthening existing collaborative networks with the University of Dar es Salaam and the Arusha Natural History Museum to promote sustainable paleoanthropological research in eastern Africa. I am now a Lecturer at Bryant University teaching ecology and sustainability courses and aim to introduce archaeology and biological anthropology courses to the university in the near future.
I earned my PhD in Archaeology from the University of Calgary, Alberta Canada. For my dissertation, I focused on the environmental context of the earliest Acheulean at Olduvai Gorge, Tanzania, and how early humans responded to different climate and environmental conditions roughly 1.7 million years ago. This was part of the Stone Tools, Diet, and Sociality project, Canada’s leading research partnership interested in the science of human evolutionary ecology. I earned my Master's degree in Environmental Geoscience and a graduate certificate in Geographical Information Systems from the University of New Haven, Connecticut, and a Bachelor's degree in Computer Information Systems from Bryant University, Rhode Island.
During my postdoc, I worked on several projects from China, Côte d'Ivoire, India, Iran, Kenya, Lesotho, Papa New Guinea, and Tanzania. In terms of my laboratory methods, I mainly use carbon and hydrogen isotopes from different organic compounds originating in plants to investigate how factors such as precipitation, plant type, and CO2 concentrations helped configure ancient ecosystems. I then compare these results to archaeological assemblages to see the ways in which humans adapted to diverse habitats in the past, both technologically and physically. I am also trying to do more modern ecosystem isotope calibration studies, such as how temperature changes associated with elevation influences plant carbon isotopes in soils. These types of studies are essential as they inform us on ecological changes throughout time and space, and how this is reflected in the isotopes from archaeological sediments.
