Stephen L. W. On received his B.Sc. from the University of East London, London, United Kingdom, and his Ph.D. from Central Public Health Laboratory/Open University, United Kingdom. Currently, he is a professor of Microbiology in the Department of Wine, Food, and Molecular Biosciences at Lincoln University in New Zealand. His research areas encompass microbiological food safety and microbial aspects of winemaking, underpinned by studies in diagnostic methods and bacterial taxonomy. His work aids basic research (e.g., genomics and virulence studies), public health (disease and outbreak diagnostics), and wine improvement (characterization of winemaking/spoilage microbes). His current research includes spectral methods for food quality and safety; foodborne pathogens, including the CHRO (Campylobacter, Arcobacter, Helicobacter, and related bacteria) group; Vibrio and Yersinia spp.; comparative genomics in taxonomic studies; characterization of winemaking yeasts for commercial advantage; and influence of the microbiome on wine character.
