Christopher directs the Public Health Policy Evaluation Unit within the School of Public Health. He is lead investigator at Imperial College for the NIHR School of Public Health Research. Christopher has published studies on a variety of topics, including tobacco control, active travel and obesity, cardiovascular risk assessment, health system performance and health inequalities. His main research interest is public health policy evaluation, with a particular interest in health inequality impacts. This includes a growing focus on evaluating strategies to prevent and manage chronic (non-communicable) disease in middle income country settings, particularly India and Brazil.

The main areas of his research currently include:

-      active travel and sustainable transport systems

-      tobacco control

-      improving the management of chronic disease 

-      financial protection in health systems
