Field work experience

I have been doing environmental science field work since the late 1990s such as looking at the effect of Trichloroacetic Acid on spruce trees and seedling in Peebles, Scotland and working as a laboratory technician at the Leibnitz Institute for Baltic Research including cruises and as a  field assistant on the Arctic Ocean 2001 Oden expedition with the Swedish Polar secretariat and later as an atmospheric chemist at Leicester University and Imperial College London. 

Publications involving peroxy radical measurement with the PERCA technique

Peroxy radical measurements help us to understand the effect of sunlight, NO2 and Volatile Organic Pollutants (VOCs) on ozone formation. They last a few seconds so measuring them involves creating a chain reaction cycle of the radicals with known amounts of CO and NO gases in a reaction chamber. NO2 is measured using chemiluminescence. Here is a short summary of peroxy and hydroxyl radicals in the atmosphere.

I was a PhD student on the measurement of peroxy radicals in remote environments (Ireland and UK)

Then used the same technique as a Post doctoral researcher researching the effect of sunlight on the absorption and retention of nitrogen gases in the snowpack at the British Antarctic Survey (BAS)'s Halley research station. I was at the old Halley station whose details you can see here.
