Stefan J Swift

I am a postdoctoral researcher in the Breath Analysis team at ETH Zurich working on the VOCORDER project. My first postdoctoral research position was based at the J. Heyrovsky Institute of Physical Chemistry in which my research focused on Selective Ion Flow Tube - Mass Spectrometry and how nitrogen may be used as a carrier gas, as well as negative ions for the reagent species for analytical applications. My second postdoc position focused on the chemical characterization and quantification of organic aerosol species using Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-ToF-MS) as part of the NASA ASIA-AQ campaign. The ASIA-AQ campaign was a two-month long mission which took place in the Philippines, South Korea, Thailand, Taiwan and Anchorage, in which I sampled ambient air from the NASA DC-8 aircraft, profiling the atmosphere, and analyzed organic aerosol online using the PTR-ToF-MS instrument coupled with a novel Chemical Aerosol Online inlet (CHARON). I completed my PhD in the Wolfson Atmospheric Chemistry Laboratories (WACL) at the University of York working with Prof Jacqui Hamilton and Prof James Lee, investigating into organic nitrogen species found in particulate matter in Beijing. I previously completed my Masters in Chemistry also at the University of York, in which I worked with Prof Lucy Carpenter, investigating into the ozone uptake coefficient at the sea surface.
