I am a probabilist.
I am currently a Prize Fellow at the University of Bath, in
the probability group ProbL@B.
From 2016 to 2018 I was the G H Hardy Junior Research Fellow at New College and the Mathematical Institute at the University of Oxford.
From 2013 to 2016 I was a PhD student in the Department of Statistics at the University of Oxford.
My supervisor was Alison Etheridge.
I am interested in population genetics models, dual processes,
solutions to partial differential equations using probabilistic techniques,
branching processes and interacting particle systems.
