Ellen Ashmore Marsh

Ellen Ashmore Marsh is a Researcher in the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge, Faculty of Mathematics. Her work applies mathematical and statistical modeling to public health and food safety challenges, particularly within New Zealand's regulatory framework.

Her research spans epidemiology, food safety, and toxicology, with expertise in source attribution of foodborne illnesses, mycotoxin surveillance, and risk assessment of chemical contaminants. She employs advanced statistical methods to analyze campylobacteriosis outbreaks, fumonisins in maize products, and heavy metal exposure in dietary contexts, collaborating extensively with New Zealand's Ministry for Primary Industries and ESR (Institute of Environmental Science and Research).

Dr. Marsh's publication record (2012-2021) shows a clear evolution from materials science toward public health applications, with 9 of 10 recent works focused on New Zealand food safety issues including pathogen source tracking, mycotoxin monitoring, and contaminant risk assessments in rice, cereals, and children's products.

No major scientific awards are documented in available sources.

Her research is primarily funded through government commissions from New Zealand Food Safety and the Ministry for Primary Industries, indicating active policy-relevant work, though specific graduate student mentorship is not publicly listed.

Dr. Marsh contributes to Cambridge's applied mathematics research ecosystem through specialized statistical modeling for food safety regulation, maintaining strong operational ties with New Zealand's public health infrastructure.
