Research Biography

Stewart Walker has worked on the design, development and application of advanced analytical techniques to solve problems in the analytical, environmental, industrial, forensic and medical arenas.  He has worked or collaborated with Industrial Companies including BP Research in London, BHP, Melbourne, Universities including  St Andrews and Glasgow in Scotland, La Trobe, James Cook, Curtin, UWA, UofSA, Adelaide and Flinders Universities in Australia and many international universities and with Government Agencies, including CSIRO, AIMS(Australian Institute of Marine Science), DSTO, Chemistry Centre WA and the CRC-Great Barrier Reef. He is a long-serving committee member and former President of the SA Branch of the Royal Australian Chemical Institute and is currently President of the South Australian Branch of the Australian and New Zealand Forensic Science Society.  He is active in consultation and has assisted AFP, SafeworkSA and SA Police on cases and as an 'International Expert' for IAEA/UN Environmental Analysis Projects in Asia.

Research Interests

Design, development and application of advanced analytical techniques (inc spectrometric, electrochemical, chromatographic and mass spectrometric) to solve problems in analytical, environmental, industrial, forensic and medical arenas.  Specialisation in combining ICPMS, LA-ICPMS and HR-MC-ICPMS for multi-elemental fingerprinting, GCMS, LCMS for compound and impurity detection and Isotope Ratio Mass Spectrometry and other techniques to identify and provenance materials including glass, paint, paper, ink, wine, food-stuffs, drugs and condoms.
