The Network in Aerosols and Health connects researchers across disciplines who are working on aerosols and provides a touchpoint for those external to the College. We aim to facilitate better aerosol characterisation (physical, chemical and biological), better source determination, better toxicological assessments, better understanding of transmission, and better understanding of drug delivery to the lungs: all with the aim to improve health. We welcome researchers working on aspects of aerosol science not primarily related to human health, including atmospheric aerosols and basic aerosol processes, and measurement techniques to promote knowledge transfer.
