Senior Technical Specialist
My research interests lie in data reduction, working mainly with the results from ToF-SIMS (time of flight secondary ion mass spectrometry) and IR (infra red spectroscopy) experiments in cell chemistry.
Chemometric and cheminformatic approaches are applied to spectra, 2D chemical images and 3D chemical hypercubes to understand the complex chemistries involved in cell structure, metabolism and drug interaction. Work carried out in parallel aims to develop visualisation tools for chemists and biologists working in this area.
Having been in the group for quite a while I find myself involved in most of the projects we have running at any one time. In addition to programming, I find myself helping out around the group, assisting with experimental technique and equipment repair.
In addition to my work in the SIMS field I also work on FTIR data of tissue as a member of Peter Gardner’s research group.
I recently taught Instrumentation for Separation Science which was a module of our Analytical and Separation Science Masters programme. My lectures covered the interpretation of mass spectrometric data.
Previously I taught Database Design and Programming on the School of Chemistry’s Cheminformatics Masters programme.
I am a director of SurfaceSpectra Ltd. and also write their software.
