Gary has over 25 years of Mass Spectrometry experience.  He started work at what was then the Rowett Research Institute in 1986, and after six weeks training in analytical techniques, started working in the Gas Isotope Ratio Mass Spectrometry (GIRMS) laboratory assisting Dr Brian McGaw and Mr Eric Milne. As interest in this technique grew, the lab eventually had four mass spectrometers dedicated to analysing the stable isotopes of Carbon, Hydrogen and Oxygen from a variety of biological sources, supporting research into energy expenditure and protein synthesis. During his time in the GIRMS lab, Gary completed part-time courses at Aberdeen Technical College and The Robert Gordon Institute of Technology obtaining his ONC, HNC in Chemistry and then becoming a Licentiate member of the Royal Society in Chemistry.  The research programmes of the Rowett then required Liquid Chromatography Mass Spectrometry (LC/MS) and a MAT 900 double-sector LC-MS/MS system was purchased in 1998, along with a LaserMAT MALDI mass spectrometer. Gary transferred to work with Dr Jim Lomax in the newly formed LC/MS Facility. Initially his role was to develop techniques for sample analysis on the MALDI, but soon Gary took over the role of managing the LC/MS mass facility. This coincided with a ‘take-off’ in the popularity of using LCMSMS in sample analysis, firstly in the growth of identifying proteins separated on 2D gels and more recently the quantitative analysis of small molecules. The main areas of analysis are in the quantification of Polyphenols relating to dietary consumption and human health and the quantification of Mycotoxins in foods and crops, in particular, the detoxification of Deoxynivalenol. The LCMSMS facility now has four mass spectrometers, with access to an ion trap to support work in these areas of research. Gary now takes the lead role in providing LCMSMS, GCMS and GIRMS facilities for RINH and the wider College of Life Sciences and Medicine.
