Biography

I am a Lecturer in Archaeological & Palaeoenvironmental Modelling at the Institute for the Modelling of Socio-Environmental Transitions. Previously I held postdoctoral fellowships at the UCL Institute of Archaeology.

I earned my PhD in 2015 from the University of Southampton, focusing on long-term patterns of hunter-gatherer land use in northern Argentina. I specialize in the archaeology and historical ecology of tropical South America, with a focus on quantitative analyses and computational modelling. I have conducted fieldwork in Argentina, Brazil, Venezuela, Colombia, and Oman.

My two principal areas of research focus on: 1) coupled human-environmental systems, and 2) computational approaches to rock art and sacred landscapes. I maintain an especial interest in spatial analysis and agent-based modelling, drawing especially on physical geography, quantitative ecology, and complex adaptive systems to understand past human societies. Recently, I have focused on the interface between climate change and ancient demography...
