Roy Harrison’s research interests lie in the field of environment and human health. His main specialism is in air pollution, from emissions through atmospheric chemical and physical transformations to exposure and effects on human health. Much of this work is designed to inform the development of policy.

Qualifications

B.Sc. (Class I Honours Chemistry) - University of Birmingham (July 1969)

Ph.D. (Organic Chemistry) - University of Birmingham (December 1972)

Biography

Roy Harrison is Queen Elizabeth II Birmingham Centenary Professor of Environmental Health at the University of Birmingham, UK, and also Distinguished Adjunct Professor at King Abdulaziz University, Saudi Arabia. His research interests are in air pollution, especially airborne particulate matter. He has also been heavily engaged at the science/policy interface as a member of several government technical advisory groups for the Department of Health and the Department for Environment, Food and Rural Affairs (Defra) in the U.K. including past membership of Defra’s Science Advisory Council. He was a contributor to the World Health Organization Global Air Quality Guidelines and the Guidelines for Quality of Indoor Air. He was appointed an Officer of the Order of the British Empire (OBE) in the 2004 New Year Honours List and elected a Fellow of the Royal Society in 2017. He is author of over 660 papers in the peer-reviewed literature, and is listed by Web of Science as a Highly Cited Researcher.

Teaching

Module Lead, Causes & Effects of Air Pollution

Postgraduate supervision

Roy Harrison has carried out pioneering research in: airborne particle concentrations and numbers in the UK; characterisation of emission and impact of ultrafine particulate matter; measurement and modelling of exposure to air toxics and verification by biomarker; high time-resolution chemical fingerprinting of particulate emissions from the steel industry; and the relationship of ultrafine and fine particles in indoor and outdoor respiratory health. Professor Harrison's recent research projects include:

Artificial chemical ageing of ambient atmospheric aerosol
Novel compact after treatment systems for simultaneous reduction of diesel engine NOx, PM, CO and HC emissions
Use of chemical composition and molecular markers to infer the sources of airborne particulate matter
Understanding the fate of traffic-generated particles

Professor Harrison has successfully supervised at least 30 doctoral researchers working in his areas of interest.
