Elias Norford
Elias trained in biomedical science before completing postgraduate study in epidemiology, where he developed a particular interest in study design, population risk, disease surveillance and the interpretation of health data. He later moved into non-clinical research communication, translating technical reports and peer-reviewed findings for general audiences and supporting editorial teams with evidence summaries and source checking.
At CAB Direct, he covers epidemiology, infectious-disease prevention, screening, vaccination evidence, community health and the interpretation of population-level findings. His writing focuses on separating association from causation, explaining uncertainty clearly and showing readers where evidence is strong, limited or still developing.
His health and medicine articles follow CAB Direct's editorial checking process before publication. Claims, statistics and source dates are checked against the cited evidence, and health content is reviewed in line with the site's editorial policy, with corrections recorded when substantive changes are required.

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.
