Dr Matthew Wright
Investigator
UK Health Security Agency
Dr Matthew Wright is a Senior Aerosol Scientist within the Nanoparticle Inhalation Research Group, Toxicology Department, UK Health Security Agency. His main area of research involves studies on the aerosol characteristics, composition, lung deposition and toxicological effects associated with exposure to a range of agents including aerosolised carbon nanotubes, e-cigarette aerosol, nanoparticle-enabled consumer products and 3D printing emissions. He is partly responsible for the design, maintenance, operation and data analysis associated with aerosol generation, measurement instrumentation, and in vitro and in vivo exposure systems.Matthew previously worked as Senior Research Associate in the Atmospheric Chemistry Research Group, University of Bristol, having obtained Ph.D. (2011) and M.Sci. (2004) degrees in Physics, also at Bristol, where research focused on a range of topics including submicron and ultrafine aerosol size distributions in urban, rural, indoor and transport environments, development of gas and aerosol tracer technologies to study dispersion (including infiltration into buildings) and chemical reactivity in the urban atmosphere. Whilst at Bristol he was also involved in studies involving air pollution measurements in a SE Asian megacity (Bangkok, Thailand), ambient aerosol electric charge state and the potential influence on lung deposition in human volunteers, and the relationship between air ions, aerosols and atmospheric electricity in urban and other environments.
Matthew has been involved with a number of outreach activities to share the group’s research with the public, including New Scientist Live and Oxford Ideas Festival, and is active within the UK Health Security Agency on the Environmental Sustainability Champions Group. He has also been an active member of the Aerosol Society throughout his postgraduate and postdoctoral career, and has served on the Committee for several years, most recently taking up the role of Treasurer in November 2020, and as a member of the Institute of Physics.

Dr Kerry Broom
Knowledge Mobilisation Manager
UK Health Security Agency
Kerry is working to mobilise knowledge generated in these three HPRUs, seeking opportunities for the translation of research into practice, policy and commercially, and strengthen the working relationships of stakeholders, the public and partners.
She has worked at the UK Health Security Agency (formerly Public Health England) for over 15 years and during that time, Kerry has provided scientific secretariat to the UK Committee on Medical Aspects of Radiation in the Environment (COMARE) and to the High-Risk Aerosol Generating Procedures Panel set up during the COVID-19 pandemic. She also has experience in scientific management of the Radiation Protection Research programme for the Department of Health.In recent years, Kerry’s role has focussed on scientific research on the neurobiological effects of exposure to electromagnetic fields (EMFs). She studied the effects of radiofrequency and power frequency field exposure on behaviour; gene expression and brain structure as well as exposure related effects on circadian rhythm control. She was involved with the international GERoNiMO project (Generalized EMF research using novel methods. An integrated approach: from research to risk assessment and support to risk management).

Dr Stephanie Wright
Theme IV Co-Lead
Environmental Research Group, School of Public Health, Imperial College London
Dr Stephanie Wright is a UKRI Rutherford Research Fellow and Lecturer in Environmental Toxicology at Imperial College London. Research in her lab focuses on the emerging topic of micro/nanoplastics and human health. With an emphasis on the air, her interests are in detection methods and exposures; biokinetics and -accumulation; and particle and chemical toxicology, all from a human health perspective.
