Current research is focused on establishing and testing a theoretical framework that identifies the mechanisms that control invasion, persistence, scaling and variability of epidemics within changing agricultural and natural landscapes. Applications range from large-scale pandemics (sudden oak death, citrus canker, African cassava mosaic virus), through pesticide resistance and genetical control to biocontrol in sustainable agricultural systems, and to the design of intervention strategies for exotic pathogen threats to the UK.

The research involves a synthesis of epidemiological theory, population and evolutionary genetics, landscape ecology and economic modelling, drawing upon methods from statistical physics and Bayesian statistical inference, supported by a complementary experimental programme involving laboratory microcosms and collation of extensive field and regional data-sets to test the models.

Teaching and Supervisions


Teaching forms part of the Natural Sciences Tripos at Cambridge in which students attend lecturers, practicals and seminars in university departments, supported by weekly College tutorials (supervisions) in each of their main subjects. Served as Director of Studies responsible for teaching arrangements in Natural Sciences (Physics, Chemistry, Biology, Materials and Earth Sciences) King's College from 1990-2004.

Currently on leave from teaching.

Previous Teaching

First year (Part IA)

  • Quantitative Biology (now Mathematical Biology) Responsible for 60 lecture course with practicals on the application of mathematics to biological problems for students with A/AS level mathematics. The course was introduced in 1990 and has grown from ~70 to ~200 students per year. The course is motivated throughout by biological questions but provides students with an extensive grounding in modelling techniques, especially ordinary differential equations, as well as statistical methods for data analysis and model testing. The course has weekly practicals for computing to illustrate modern methods of numerical solutions as well as more traditional examples classes for analytical solutions.
  • College supervisions in Quantitative Biology, Maths for Natural Sciences, Elementary Maths for Natural Scientists, Evolution and Behaviour

Second year (Part IB)

  • Plant and Microbial Sciences Previously contributed lectures and practicals on Epidemiology and Modelling to IB Plant Science students.
  • College supervisions in Part IB Plant Sciences, Ecology

Third year (Part II)

  • Plant Sciences Lecture course on Botanical Epidemiology, with accompanying projects to Part II Plant and Microbial Science students. Previously taught courses in experimental design, spatial analysis and sampling theory.
  • College supervisions in Part II Epidemiology and Statistical methods
