Ellen Marsh

Ellen writes Health & Medicine explainers for CAB Direct, with a focus on public health, disease prevention and the interpretation of medical research for general readers. Her academic background combines biomedical sciences with postgraduate study in population health, providing a foundation in human biology, epidemiology, health data and the factors that shape health outcomes across populations.

Her editorial work covers preventive health, screening, epidemiological evidence, common health conditions and the interpretation of clinical and population-level studies. Before joining CAB Direct, she worked with research-based health content and evidence summaries, developing experience in translating technical findings into clear, accessible explanations while preserving the limits and context of the underlying evidence.

Her CAB Direct articles follow the site's editorial process, with factual and scientific claims checked against appropriate medical and research sources. Health content is reviewed in line with CAB Direct's editorial standards before publication, with corrections and evidence updates handled through the site's established review process.
