Ben Ashby

I am a mathematical biologist interested in the ecology and (co)evolution of hosts and their parasites. I use mathematical models and simulations to study how parasites spread through populations and evolve traits such as infectivity and virulence, and in turn how this affects the evolution of host traits such as resistance or mating strategies. My research covers a broad range of topics in biology, including the evolution and maintenance of diversity across space and time, sexual selection and reproductive strategies, and niche evolution. In my spare time I enjoy running, hiking and nature photography.

I am a mathematical biologist who is interested in population dynamics and epidemiology, and applying stochasticity to mathematical models. I will be completing my PhD in developing spatially extended hybrid methods at the University of Bath in early 2021, and am looking forward to getting started with the group in January. Outside of maths, I attempt to play football, enjoy taking walks and singing.

PhD students

Lydia Buckingham

Lydia BuckinghamMy research investigates the ways in which pathogens and their hosts co-evolve to create different age-structured patterns of immune responses in the host. I have just finished my undergraduate degree in Mathematics at Merton College, Oxford, with my Master’s project focusing on the effects of host heterogeneity on the spread of infectious diseases. In my spare time, I enjoy playing the piano and looking after my small flock of sheep.

Yvonne.JPGI am generally interested in eco-evolutionary processes and mathematical modelling of population dynamics. More specifically, I investigate the evolution of sexual reproduction in an ecological context subject to demographic noise. In 2018, I finished my master’s degree in Physics with specialisation in Complex Adaptive Systems at University of Gothenburg, Sweden. The project I have been working on considered an attraction-repulsion model for collective motion including anticipation. Besides maths and programming, I like learning new languages and enjoy hiking, bird watching, or cosy film and board game evenings.

My research is focused on coevolution between hosts and STIs using mathematical models and computer simulations. I have recently finished my undergraduate degree, (MMath) Mathematics with International Study, at the University of Exeter. During this time I studied at the University of New South Wales in Sydney, where my interest in mathematical biology was sparked. I also completed a research internship at the University of Exeter, where I looked into how the heterogeneity of neuronal cells could be modelled by Hodgkin-Huxley computational models. I spend a lot of my free time kayaking, mountain walking, and swimming.

Jason Wood

poss_profI am interested in using mathematics to help develop our understanding of eco-evolutionary systems, especially using computational methods. My current research investigates the coevolutionary dynamics of systems with three species involved; at the moment I am considering a Host – Parasite – Hyperparasite system. I completed my undergraduate degree in Mathematics and Physics (MMath) at the University of York in 2018 and my Master’s project focused on the swimming of microorganisms. In my spare time I like to read, take latin and ballroom dancing lessons, and play the niche sport of underwater hockey.

I joined the pack group in August 2020. I’m still young, but I’m growing fast and will be working hard on my recall skills and house training over the next few months. I have broad research interests and am keen to investigate anything new.
