Joe Hilton

I am currently a PhD Student with the Mathsys CDT, supervised by Matt Keeling(Maths, Life Sciences, Zeeman Institute) and Ian Hall(University of Manchester). My research is in epidemiology, with a focus on stochastic models for both novel and endemic diseases in structured populations. Outside of my PhD project, I am interested in using maths to answer questions everywhere from ecology to linguistics to public policy.

PhD Project(s)

My PhD follows two main threads:

  • Endemic diseases in structured populations. The use of age- and household-structured models for childhood diseases such as measles and mumps is well established. However, these infections tend to circulate over long timescales, during which the underlying contact structures can change dramatically, with children growing into adults and moving between different households. My work in this area focuses on developing structured infection models with dynamic population structure, informed by real-world data from statistical agencies and contact surveys.
  • Behaviour of early outbreaks. The early behaviour of an epidemic is well-approximated by a relatively simple class of stochastic model known as a branching process, which focus on the spreading behaviour of early cases. During my PhD I have considered the effect of household structure on this spreading behaviour and how well different probability distributions can account for the distribution of cases generated.

Research internship: Modelling Infection, Household and Demographic Change

I worked with my PhD supervisor Matt Keeling on a three month research internship (October-December 2016) supported by the EPSRC Global Challenges Research Fund. Our focus was on developing a model for the spread of an endemic disease which included accounts for both age and household structure. This project formed the basis of the "Endemic diseases" section of my PhD.

IMA Small Grant Scheme, awarded December 2018 by the Institute of Mathematics and its Applications in order to fund my attendance at the 10th Swedish Meeting on Mathematics in Biology.

Background and Previous Projects

Before joining the MathSys CDT, I completed my MMath at Warwick, graduating with first class honours in 2014. I graduated from the MathSys MSc in January 2016. My research experience during this time includes the following projects:

  • Branching Process Models for Weakly Transmissible Diseases, supervised by Matt Keeling and Ian Hall
  • Critical Community Size and Extinctions for Livestock Disease, supervised by Matt Keeling and Simon Gubbins (Pirbright)
  • Levins Metapopulation Dynamics for Stochastic Populations, supervised by Matt Keeling
  • Behavioural Epidemics with a Complex Stifling Contagion, supervised by Thomas House (then Warwick, now at Manchester) and Daniel Sprague (then Warwick, now at Spectra Analytics)

Other activities

Teaching

I was seminar tutor for the module "Population Dynamics: Ecology & Epidemiology" in the 2016-17 and 2017-2018 academic years.

Warwick SIAM Chapter

From 2015-2017 I was on the exec committee of Warwick's student chapter of SIAM, the Society for Industrial and Applied Mathematics. Our focus is on engaging students and stimulating discussions focused on applied and computational mathematics. We host regular talks featuring speakers from industry, as well as mini-conferences which bring together the worlds of industry and academia and give students a platform to present their research. All members of our student chapter are eligible for a free SIAM membership, giving them access to journals, newsletters and online resources.
