My research is focused on halogens and radical chemistry in the troposphere, combining measurements and modelling. My main research project is about the processes that form and destroy ozone, and other pollutants, in the lower atmosphere.

I obtained my PhD in Chemistry from the University of Leeds (2005). After that, I worked at NOAA (Boulder, CO, USA) for four years working on nighttime chemistry. I  then moved to UEA (Norwich, UK) to work on halogen chemistry, and continued my work on the subject at the University of Leicester (UK).


Researcher identifier number: M-5361-2014

Research interests

Radicals and haloge chemistry in the troposphere; formation and evolution of atmospheric pollutants; chemical mechanisms and models for atmospheric chemistry; chemical ionization mass spectrometry
