David Walker
Senior Scientist - Environmental Virology
Dr David Walker has several years of experience in food safety and water quality, specialising in microbiology and virology, particularly enteric pathogens, faecal indicators, and respiratory pathogens in shellfish and water. His current focus is on quality assurance for methodologies and data for environmental surveillance of pathogens. This has involved the development of a programme of interlaboratory ring trials, the provision of high-level and detailed technical advice to government and academic partners and the development of protocols for quantifying pathogens in wastewater. He is currently creating a framework for the development of new surveillance programmes to ensure they provide robust data that can be used to guide policy decisions.
