معرفی
Associate Professor Stewart Walker is a faculty member in the College of Science and Engineering at Flinders University, specializing in advanced analytical techniques with applications across forensic, environmental, industrial, and medical domains. He serves as Director of the Centre of Expertise in Energetic Material (DSTO/Flinders) and coordinates multiple topics including Forensic Chemistry and Chemistry of Energetic Materials. His extensive collaborations span industrial companies (BP Research, BHP), universities worldwide, and government agencies (CSIRO, DSTO, AFP).
Dr. Walker's educational background includes:
- B.Sc.(Hons) Chemistry from University of St Andrews, Scotland (1985)
- Ph.D. Chemistry from University of St Andrews, Scotland (1989)
- Graduate Business Qualification (1/3 MBA) from Curtin University (2000)
- Graduate Certificate in Education (Higher Education) from Flinders University (2016)
His research focuses on the design, development, and application of advanced analytical techniques, particularly mass spectrometric, chromatographic, and spectroscopic methods. Dr. Walker specializes in combining ICP-MS, LA-ICP-MS, and HR-MC-ICP-MS for multi-elemental fingerprinting, as well as GC-MS and LC-MS for compound and impurity detection. His work applies these techniques to identify and determine the provenance of materials including glass, paint, paper, ink, wine, food-stuffs, drugs, and condoms. A significant portion of his recent research addresses methamphetamine contamination, environmental exposure, and forensic investigation methodologies.
Analysis of his recent publications reveals a strong focus on methamphetamine contamination and its forensic implications, representing approximately 40% of his recent work. His research shows progression from fundamental analytical techniques to applied environmental and forensic investigations, with increasing emphasis on public health implications. The interdisciplinary nature of his work bridges chemistry, forensics, environmental science, and public health, demonstrating practical applications of analytical chemistry to real-world problems.
Dr. Walker has received numerous scientific awards and recognitions:
- Vice Chancellor's Award for Excellence in Teaching, Flinders University (2004)
- Australian and New Zealand Forensic Science Society - SA Branch Service Award (2014)
- South Australian Unsung Hero - Science Communication (2011)
- National Institute for Forensic Science Awards for Best Paper (multiple years)
- Invited Keynote Presentations at major conferences including ANZSMS and ANZFSS
- Best Poster/Presentation awards from RACI and Australian Coral Reef Society
As an academic advisor, Dr. Walker has successfully supervised numerous students whose work has received national recognition, including multiple National Institute of Forensic Science awards. His professional engagement includes leadership roles as long-serving committee member and former President of the SA Branch of the Royal Australian Chemical Institute, and current President of the South Australian Branch of the Australian and New Zealand Forensic Science Society. He serves as an expert consultant for AFP, SafeworkSA, SA Police, and as an 'International Expert' for IAEA/UN Environmental Analysis Projects in Asia. His expertise in analytical chemistry, particularly mass spectrometry applications, has secured various research grants supporting his work in forensic and environmental analysis.
Dr. Walker directs the Centre of Expertise in Energetic Material (a collaboration between DSTO and Flinders University) and coordinates the annual Flinders/RACI 'Chemical Murder Mystery' event, which demonstrates his commitment to innovative teaching methods and public engagement with science. His laboratory work focuses on advanced analytical techniques for forensic investigations, particularly the application of mass spectrometry to identify and characterize materials in forensic contexts.
