My research interests

My work involves developing, validating and deploying mathematical models across a range of diseases, including:

  • COVID-19
  • Malaria
  • Neglected Tropical Diseases
    • Lymphatic filariasis
    • Soil-transmitted helminths

I aim to publish all relevant code on GitHub and co-wrote a peer-reviewed article on unit testing and responsible modelling for infectious diseases in 2020. My experiences working within the JUNIPER consortium (pandemic modelling) and the NTD Modelling Consortium have demonstrated that collaboration is a key to reproducible and robust science, so if you’re interested in working with me then please get in touch, I’d love to hear from you!

Recent research projects

COVID-19 Test Trace and Isolate in the UK

We developed an individual-based stochastic model of COVID-19 transmission, considering variable infectivity relative to time of infection. By considering testing and isolation behaviours, our results demonstrated that adherence and symptom reporting are the most important factors when assessing the potential impact of contact tracing efforts.

Lymphatic filariasis elimination

Simulating vector-borne transmission of lymphatic filariasis as a branching process showed the importance of parameterisation when calculating population breakpoints. Extinction probabilities are highly dependent on key parameters, such as the probability a juvenile parasite will survive maturation in the host and the annual mosquito biting rate.

A compartmental mosquito feeding-cycle model

By combining a compartmental gonotrophic cycle model of the mosquito population with an SEI infection model, we investigated the differential effects of vector-based interventions targeting larval and adult stages on the mosquito population dynamics to assess the mechanisms for reducing transmission of vector-borne diseases, such as lymphatic filariasis and malaria.

Seasonal timing of treatment for soil-transmitted helminths

We incorporated seasonal forcing, due to environmental fluctuations in rainfall and temperature, into a deterministic mean worm burden model of ascaris lumbricoides transmission to assess the impact of mass treatment timing. We used ABC to fit the model to prevalence data from a range of locations to conclude that optimal treatment timing coincides with the minima of the external larval population.
