Dr Eulyn Pagaling is a Senior Environmental Microbiologist. Her research focuses on environmental contaminants, particularly on the antimicrobial resistance-pathogens-microplastics nexus, using molecular approaches to tackle these challenges. This research includes determining sources and transmission pathways, understanding mechanisms involved in transmission and persistence, and understanding how contaminants can impact the environment.

Dr Eulyn Pagaling was awarded her PhD in Environmental Microbiology in 2008 from the University of Leicester, where she investigated the microbial ecology of salt lakes and hot spring microbial mats in China, including the discovery of novel viruses that infect Halorubrum kocurii. She undertook a postdoctoral position at the University of Edinburgh, where she used the Winogradsky column as a model system to investigate factors affecting microbial community assembly and microbial community composition. She then moved to the University of Hawaii at Manoa, taking up a position in the Department of Civil and Environmental Engineering, where she was involved in various projects on microbial ecology in natural and engineered environments such as anaerobic digesters, microbial fuel cells and municipal sewage systems. She received her appointment at the James Hutton Institute in 2015.

Co-PI on JHI-B6-1 (RESAS): ‘Flows of antimicrobial resistance and pathogens through the environment to the food chain’ 2022-2027. I co-lead this project, which aims to quantify the flow of antimicrobial resistance genes and pathogens from the environment to the food chain and directly to humans in the farm environment. This will be integrated with social science work to understand the perceptions farmers have of the link between antimicrobial use and antimicrobial resistance. Both quantitative and qualitative data will be used to develop a risk assessment model based on the source-pathway-receptor principle.

Hutton PI on MRI-A2-2 (RESAS): ‘Role of transmission and pathogen components in virulence and disease pathogenesis for important endemic diseases of livestock in Scotland’ 2022-2027. I am Hutton lead on a project investigating the environmental prevalence of Mycobacterium avium paratuberculosis (Map) (the causative agent for Johne’s Disease in livestock). The project will investigate the drivers of Map transmission, transmission routes from the environment to healthy livestock and the effectiveness of control programs to mitigate the spread of Johne’s Disease.

WP lead on JHI-D2-1 (RESAS): ‘Emerging water futures’ 2022-2027. I lead the work package on increasing the resilience and quality of private drinking water supplies. This project will combine qualitative social sciences methods with risk mapping, feasibility assessments and somatic coliphage test development to build an interdisciplinary understanding of the risks, impacts and responses that arise from growing uncertainty and variability in rural drinking water supplies.
