PhD (Ohio State University)
Postdoctoral research fellow at the University of Leeds, working on THz spectroscopy
My research in the Bristol Laser Chemistry Spectroscopy & Dynamics group is focused on the structure and reactivity of Criegee intermediates. Criegee intermediates are produced in the atmosphere following ozonolysis of alkenes. I will be using cavity ring-down spectroscopy (CRDS) to probe Criegee intermediates in the time and frequency domains. Results from this research will be used in atmospheric modelling studies, in collaboration with Prof Dudley Shallcross.
My previous work was focused on the spectroscopy of reactive intermediates important in atmospheric and combustion chemistry. I used several techniques like CRDS and laser induced fluorescence (LIF) spectroscopy in bulk and jet conditions to probe free radicals and stable molecules.
