Biography
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. 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. Initially his role was to develop techniques for sample analysis on the MALDI, but soon 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 targeted quantitation 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.
Other Areas of interest include:
- Vitamin D3
- Methylamines
- Anthocyanins
- Nicotinamides
- Carboxymethyl Lysines
- Antibiotics
