Toxicologists study how chemicals, drugs, and other substances affect living systems, and at what exposure levels effects appear. The work supports safety assessment for medicines, chemicals, and consumer products, as well as forensic and clinical investigation. Regulatory toxicology in particular involves close work with defined testing frameworks and dossier requirements.

Epidemiologists study patterns of disease and health in populations and what explains them. The work is largely quantitative (study design, surveillance data, and statistical analysis), and it feeds directly into public health decisions. Outbreak roles can be intense and time-pressured; surveillance and research roles are steadier.

Forensic scientists analyse physical evidence and report what it does and does not show. The work is procedurally strict (continuity of evidence, validated methods, and contamination control) because findings may be tested in court. Casework is mostly laboratory-based, with report writing and occasional expert testimony.
