Photoinitiated Processes in Aerosols
The goal of this project is to resolve the factors that govern light-initiated processes in atmospheric aerosols. Although both sunlight and aerosols are ubiquitous, the chemistry driven by their interaction and the resulting effects on climate and health relevant aerosol properties are poorly known.
Surface Composition of Droplets
The goal of this project is to measure the interfacial composition of picolitre volume droplets. Atmospheric particles have extremely high surface to volume ratios, and the particle-air interface is key to a range of processes, like cloud droplet formation. We are developing approaches to measure directly the dynamic properties at the droplet interface and collaborating with modellers to develop predictive tools to describe aerosol surface composition.
