About Me

My work aims to develop a better understanding of the physical and chemical properties of aerosol, both of which are important factors in determining their influence on climate, as well as their dynamics in numerous other applications (e.g. pulmonary drug delivery, spray drying).

I completed my PhD at the University of Bristol, UK, in 2014 under the supervision of Prof Jonathan Reid. My research focused on exploring the vapour-liquid partitioning of volatile and semi-volatile species in aerosol. I developed techniques to measure the evaporation rate of single droplets and applied thermodynamic and kinetic models to interpret observations in terms of their microphysical properties. Specifically, I showed how aerosol hygroscopicity could be determined at water activities approaching saturation using the evaporation kinetics, and demonstrated how surface films may influence evaporation by perturbing the surface transport kinetics.

My research as a postdoctoral research scholar at the Advanced Light Source under the supervision of Dr. Kevin Wilson builds upon my experience of the physical state of aerosol. I explore the influence of the condensed phase state on chemical oxidation dynamics, using a combination of aerosol ensemble and single particle methods coupled with mass spectrometry (DART-MS) and photoelectron spectroscopy.
