Interactive models and decision-support tools developed from my research and collaborations.
Math Bio Surfers turns my mathematical biology course notes into a four-level revision game. Choose a chapter, answer questions, arrange modelling steps and tackle common misconceptions. Runner mode adds a challenge across three lanes, while Study mode offers untimed practice with explanations.

There are many simulators of the logistic map, but few bring its trajectories, cobweb plots and bifurcation structure together. This Shiny app lets you simulate two trajectories at the same time, compare their cobweb plots on common axes and interpret the dynamics using the central bifurcation plot.

Predicting the spread of COVID-19 in educational settings is complicated, not least because children are frequently asymptomatic. Josh Moore and I developed an individual-based simulator so that policy-makers could compare the predicted effects of different interventions. The work was supported by a JOGL microgrant and is described in our research paper. Read the research.

Lucy Henley, Josh Moore and Tim Ostler created this tool during the NERC 2020 Hackathon. It uses a greedy algorithm to place passengers and their distancing zones, showing the tension between safe capacity and the environmental performance of public transport. The team won the competition and submitted the work as written evidence to Parliament. View the source code or read the parliamentary evidence.

Paul Harper, Josh Moore and I were asked by the Welsh Government to estimate how many secondary cases university students returning home might generate over Christmas. The app lets users vary transmissibility and explore the resulting number of secondary cases. Read the research.
