Modelling and Biostatistics Group

Head: Professor David Wilson


Our dynamic, interdisciplinary team works at the forefront of optimising maternal and child health, nutrition and infectious disease programs.

We use our models to generate scientific evidence to guide policy decisions across a range of public health issues, including:

  • infectious disease control and elimination
  • program implementation
  • strategic planning
  • resource optimisation.

In close partnership with the World Bank we have developed a collection of ‘Optima’ models to link interventions and their costs with their impact, perform scenario analyses, predict epidemiological trends and optimise spending.

Optima tools have already been used by over 40 countries across Eastern Europe, Asia, South America, and Africa to guide resource allocation towards the most cost-effective mix of programs, and to assist with national strategic and operational planning.
