We are proud of our Athena Swan Silver Award and strive to provide a working environment which facilitates wellbeing and allows all staff and students to contribute fully, flourish, and excel. We aim for a sustainable future. Role This position is part of the UKRI-funded interdisciplinary project RATTUS: Rats and the Archaeology of Trade, Urbanism, and Disease in Past European Societies, led by David Orton in the Department of Archaeology. The Research Associate in Mathematical Modelling will work with colleagues in Archaeology, Biology, and History to help investigate the history of black and brown rats in Europe, aiming to understand rats’ association with human settlement and communications and their role in disease. This position will be focused on modelling rat population dynamics across dynamic networks of urban settlements representing historic Europe, informed by rat life history, zooarchaeological data on rodent presence, settlement types and climate, stable isotope data characterizing rat resources, and archaeogenetics assessing population histories and connectivity across time and space. The models will be based on existing patch-based, differential equations for rodent dynamics in response to pulsed resources. The Research Associate will bring models and data together to (1) explore how settlement form, trade, climate, and disease interacted to determine viability of past European rat populations, (2) explore different scenarios of economic and settlement change and (3) understand rat population stability and turnover with respect to plague. In collaboration with other members of the RATTUS team, the Research Associate will disseminate findings at conferences and submit manuscripts to peer-reviewed journals. The Research Associate will have the opportunity to contribute to supervising undergraduate and postgraduate projects.
