Theme 2 - Modes of toxicity (Biochemical pathways from toxin to disease)

Public Health England

Matthew is Senior Aerosol Scientist in the Nanoparticle Inhalation Research Group, Toxicology Department, at the Centre for Radiation, Chemical and Environmental Hazards, Public Health England, UK.

He obtained an M.Sci in Physics with Industrial Experience from the University of Bristol in 2004, and a Ph.D. in Physics, also from Bristol, in 2011 with research focusing on urban submicron particulate air pollution. He joined the Atmospheric Chemistry Research Group, School of Chemistry, University of Bristol in 2011, working under Professor Dudley Shallcross. There he undertook work on the lung deposition of ultrafine particles in human volunteers (in collaboration with the National Heart and Lung Institute and Imperial College London); the effect of electric charge on atmospheric aerosol dynamics and the links between atmospheric electricity and airborne particulate pollutant characteristics; and using tracer gases to study urban atmospheric dispersion and infiltration of pollutants into and around the indoor environment.

In 2015 he was awarded a British Council/Newton Fund Researcher Links Travel Grant allowing him to undertake a collaborative research visit to the Laboratory of Environmental Toxicology, Chulabhorn Research Institute, Bangkok, Thailand, where he studied ultrafine particle number concentration and the metal composition of submicron particles.

In 2017, Matthew joined PHE as Senior Aerosol Scientist, where he has responsibility for maintaining and developing capability for in-depth aerosol characterisation and undertaking related research. Current research projects include the characterisation of nanoparticle-containing consumer spray products in realistic exposure situations; assessment of the toxicity of multi-walled carbon nanotubes (MWCNT) in relation to physical properties including size, shape and effective density; and the dynamic characterisation of gas and particulate components of e-cigarette emissions in an in vitro exposure system reflecting expected aerosol thermodynamic behaviour in real-world use.
