Paul is Director of the Centre for Health and Environmental Management Research and Innovation (CHEMRI) in the School of Management and leads the Respiratory Diagnostics Group in Medicine. A primary focus for CHEMRI is the analysis of large-scale environmental data and impacts on health and wellbeing of citizens, particularly in areas of higher deprivation. Key research involves the development, evaluation and implementation of new low-cost and sustainable technologies for air quality monitoring, modelling of environmental and health data for impact assessment and application of large scale analytics including machine learning and multivariate statistical techniques. Working closely with local authorities and industry, Paul's team have a special interest in modelling and assessing impact of particulates including PM10 and PM2.5 in urban areas and industry and generating evidence for policy change.
His respiratory research involves the development and application of optical spectroscopy for high-throughput and low-cost diagnostics. He has led, and been involved in, a number of clinical trials and studies involving health boards and trusts across the UK. His work has led to the filing of three patents and the formation of a number of spin-out companies in the field of diagnostics and air pollution monitoring and analytics.
Paul has research collaborations with a number of health boards across Wales including Swansea Bay UHB, Cwm Taff UHB, Hywel Dda UHB and Cardiff and Vale UHB. As a principal investigator and co-investigator he has been involved in generating over £6 million in external research grant funding.
