I received my undergraduate degree at California State University, Fresno, before coming to the University of York’s Department of Mathematics for a PhD in Mathematical Modelling on a departmental teaching studentship. My PhD work was with the York Historical Warfare Analysis Group, where we examined and modelled historical war data to better understand human conflict. I currently am working as a post-doc with the Leverhulme Centre for Anthropocene Biodiversity, where I work on mathematically modelling changes and trends in biodiversity. My current primary project is on the movement of species and communities affects their biodiversity.




My current research with Dr Jon Pitchford, Prof. Susan Stepney, and Prof. Chris Thomas focuses on ecosystem and species dynamics. We seek to investigate how the movement of species, including direct human intervention, affects the biodiversity of both the local environment and the broader region. As such, my interests mathematically primarily lie in the fields of computational mathematics, dynamical systems, and data analysis. More broadly I am also interested in applications of mathematics, including graph theory, game theory, and causality.
