Microorganisms are an important but often misunderstood form of life. The causative agents of many diseases, microbes can also be exploited as "cell factories" to produce a wide range of useful products, provide the means to decontaminate polluted environments and act as models for understanding biological processes. At York you will learn about the practical application of biological knowledge to economically important areas, such as health, food and the environment. Our modules are assessed by a combination of closed examinations and openly assessed work. We design our exams to assess conceptual understanding as well as important facts about the subject. The exams also contain problem-solving questions which we think should be fundamental to any scientific discipline. Openly assessed work is typically based on practical classes, and may take the form of a practical write-up or problem questions. Employment opportunities are diverse, ranging from biological and biomedical research and development, to careers in science communication, the health service, forensic science, environmental health and wildlife conservation. Our graduates are not confined to science-related careers, and a significant number enter jobs within finance, public and private sector management, social and health service work, the media and law.
