Andrew Clark BA MA

Assistant Professor in Health Decision Modelling


I joined the LSHTM in 2002. I have a background in computer science, mathematical modelling and economics.




Module Organiser for Analytical Models for Decision Making (distance learning). Tutor on the Public Health Masters Degree programme (in-house).


Developing computer models to help decision-makers make evidence-based choices about new and under-utilised vaccines. These models are funded by the World Health Organization and GAVI Alliance and evaluate the costs, health impact and cost-effectiveness of haemophilus influenzae type b (Hib) vaccine, pneumococcal conjugate vaccine (PCV), rotavirus vaccine (RV) and human papillomavirus (HPV) vaccine. The models have been used by Ministries of Health in Albania, Argentina, Azerbaijan, Belarus, Bolivia, Costa Rica, Croatia, Ecuador, Egypt, El Salvador, Georgia, Guatemala, Honduras, India, Iran, Jamaica, Kenya, Nicaragua, Pakistan, Panama, Paraguay, Peru, Senegal, Uganda, Ukraine, Uruguay and Uzbekistan. The models range from very simple Excel-based decision models through to more complex individual-based (micro-simulation) transmission models. The models have also been used at the global level to inform recommendations made by WHO's Strategic Advisory Group of Experts (SAGE).
