This degree is targeted at potential academics, specialists or professionals in the field of occupational hygiene, environmental health, environmental sciences, chemistry, toxicology, physiology etc., with a scientific interest to bridge these fields.

Human exposure science entails the study of human contact and interaction (exposure) with chemical, physical or biological stressors occurring in their environments, and advances knowledge of the mechanisms and dynamics of events either causing or preventing adverse health outcomes. This MSc Med degree covers the principles of exposure science, focusing on understanding the exposure pathway, i.e. from source to the receptor via compartments such as air, water, in order to develop effective interventions to prevent exposure. The fundamental focus is the relationship between environmental and occupational exposures (i.e. to the general public, consumers, residents, workers) over the entire lifetime of a human being, and the potential impact on the health of communities and workforces. The degree also incorporates occupational hygiene and environmental health practices, which can be considered sub-specialisms of exposure science, however with a focus on controlling exposures.

The expected output levels/competencies are academically trained professionals/ specialists/scientists in occupational and environmental hygiene (national health and environmental departments and services, consultancies, private and non-profit sectors, academia, etc.)


MSc Med Exposure Science by coursework and research (Programme code MCA08):

This comprises three parts:

a) Part 1 (coursework) consists of five one-week long courses in the form of interactive lectures, and practical, as well as on-line sessions covering the following topics: Introduction to Occupational & Environmental Health, Exposure-induced Health Outcomes, Exposure Science I (Principles), Fundamentals of Risk Assessment, and Exposure Control I (Fundamentals). These courses are offered in Year 1 of the Programme.

b) Part 2 (coursework) consists of five one-week long courses in the form of interactive lectures, and practical, as well as on-line sessions covering the following topics: Exposure Science II, Exposure Assessment Methods I, Exposure Assessment Methods II (Data Analytics and Analysis), Computational Exposure Assessment and Exposure Control II (Applications). These courses are offered in Year 2 of the Programme.

c) Part 3 is a research project in the field of Exposure Science, and is conducted across Years 1 and 2 of the Programme.

The coursework contributes 70% and the research 30% to the overall Programme.

MSc Med Exposure Science by research only (Programme code MRA05):

Applicants with proven research experience in an appropriate field will be considered for the MSc Med Exposure Science research track. Although no coursework is required, students can choose to attend any of the courses for credit, at an additional cost. Alternatively, modules can be undertaken by observation only (non-credited) at no charge. The latter option depends on availability of space on the Programme, and is not guaranteed. Depending on prior experience, students will be required to register for particular courses, to ensure that they gain the required relevant knowledge and skills.
