Rate My Professor Russell Frew

Frew's research focuses on trace metals in natural waters, stable isotope geochemistry, paleo-chemistry, and geochemical provenancing. Current projects investigate geographical origins of foods such as honey, coffee, soybean, hops, and edible oils using stable isotopes, trace elements, volatiles, and statistical methods; and nitrogen fluxes in oceans via isotopic tools. With over 192 publications, his work has garnered more than 8,000 citations and an h-index of 46. Key publications include 'Multi-source data fusion for soybean origin traceability: Stable isotopes, elemental composition, & volatile organic compounds' (Food Chemistry, 2025), 'Near-infrared spectroscopy combined with multivariate analysis for the geographical origin traceability of New Zealand hops' (Food & Bioprocess Technology, 2025), and 'Non-linear machine learning coupled near infrared spectroscopy enhanced model performance and insights for coffee origin traceability' (Journal of Near Infrared Spectroscopy, 2024). His contributions earned the Shimadzu Prize for Industrial and Applied Chemistry (2019, NZIC), IAEA/FAO Merit Award for Outstanding Performance (2014), and a 2012 University of Otago research distinction. Frew's innovations have influenced supply chain traceability across food, fashion, and pharmaceuticals.
