Research

I’m currently a doctoral student with Hildegard Uecker, working on mathematical models of the population genetics of bacterial plasmids and of other extrachromosomal genetic elements, particularly the evolutionary implications of multicopy plasmids carrying distinct alleles. A motivating example is the contribution of multicopy plasmids to the evolution of multiple-drug resistance, for which I have developed a stochastic evolutionary rescue model. You can find an overview of some of my work so far in a graphical abstract and a poster.

My general research interests are in applications of mathematics, particularly probabilistic and stochastic models, to problems in ecology and evolution. I previously did an MSc with Tom Sherratt working on models of optimal predator behaviour under uncertainty.
