    Explore the hidden world of microbes and discover how they shape life, health and our planet.

    Why study Microbiology?

    Microbes make up over half of all life on Earth – tiny, unseen, and endlessly fascinating. At Otago you’ll learn how microbes influence human health, ecology, industry and global systems. From how our immune system responds to infections, to how microbes help recycle nutrients or even produce food and medicines, this subject opens doors across biology, health and environment. You’ll get hands-on with lab work in modern facilities, build real-world skills and explore questions that matter now and into the future. With the Department of Microbiology and Immunology at Otago conducting world-class research, you’ll be part of a vibrant community investigating microbes, immunity and disease.

    Career opportunities

    When you study microbiology you open pathways into many exciting careers. You’ll build strong scientific skills, analytical thinking and practical lab experience. Possible careers include:

    • Microbiologist in healthcare or diagnostic labs
    • Research scientist in biotechnology or pharmaceuticals
    • Agricultural microbiologist
    • Quality assurance or food safety officer
    • Science communicator or educator

    How you will learn

    At Otago you’ll start with a broad foundation in biology and chemistry, then move into specialist microbiology and immunology papers where you’ll spend time in labs, working on microbes, infections, genes and ecosystems. In your third year you’ll collaborate with peers, tackle research challenges and develop your research communication skills alongside your science.

    Recommended high school subjects for undergraduate study

    A strong foundation in Biology and Chemistry in your final year of secondary school, or equivalent, will help you succeed in first-year papers.
