Google Scholar Profile


I lead the Process and Systems Modelling team at BioSS as well co-leading the Large Scale and Sectoral Modelling theme on the RESAS strategic research programme. I develop process-based models of biological systems, generally using ordinary or delay differential equations. Since joining BioSS my research has focussed on two main topics - microbial communities and crop pests (see below).

I am also the Open Science Champion at BioSS. Sharing my work is others is very important to me and I endeavour to release all of my code in user-friendly packages where possible - please see my software page and my github repo for more info.

Current research

Modelling Microbial Communities

I am interested in the dynamic modelling (based on ordinary differential equations) of microbial communities in the human colon. Particularly in modelling the emergent dynamics of these complex systems.

      Modelling Crop Pathogens

      I have worked on a number of projects involving modelling crop pests, e.g., potato cyst nematodes (PCN), rice pests (LEGATO project) and more recently the cabbage stem flea beetle. These all involve stage-structured populations which I model using time-delay differential equations or integro-differential equations. I have written an R package (stagePop - see below) which solves these type of equations for a wide range of pests and can also include pest-predator-parasitoid interactions.

      Software: stagePop: an R-package to model stage-structured populations and any number of interacting populations (e.g. parasitoids and predators).

      Outside of work I enjoy running, cycling and hiking!
