Our main research activity is in occupational and environmental exposures and their
effects on health, for example, air pollution and cardio-pulmonary disease, occupational exposures and lung disease. We also consider how disease can impact on work capability, and in how knowledge of the effects of work or the wider environment feed into policy development.
Our Research Group
The group is divided into two sub-groups: Work and health and environment and health.
The work and health group assess the interaction between exposures (mostly by the inhaled route) and the development and/or exacerbation of lung disease. Examples are the development of occupational asthma and occupational COPD and work factors which influence management of these conditions. This group also works on the effect of having lung disease on work capability (both COPD and asthma) and on factors governing the under-recognition of occupational asthma.
The Environment and Health group are mainly focussed on the effects of both indoor and outdoor air pollution on health integrating epidemiology with field studies which incorporate area and personal exposures and specific toxicology of particulates from certain sources. Their work covers both the developed and developing world, with studies in the latter area in Nepal and Malawi specifically on smoke exposure from biomass fuel burning in unventilated homes. They are also involved in studies around the health effects of pesticides and have a growing area of research in nano-materials and health.
Both groups also feed information and expertise into the development of policy through the HSE, HPA, DEFRA and DWP.
