Research

My interests lie in the interdisciplinary field of aerosol science with an emphasis on aerosol characterisation and aerosol chemistry. In the research lab we routinely use optical trapping and spectroscopy techniques as well as dynamic vapor sorption measurements for hygroscopic and volatility studies on a range of compositions.
