    Why study Molecular Basis of Health and Disease

    If you're curious about how health and disease begin at the molecular level, this major is for you. Studying Molecular Basis of Health and Disease gives you a front-row seat to the inner workings of cells and how they communicate, grow, adapt, or sometimes malfunction. At Otago, you’ll explore real pathways that go awry in cancer, diabetes, heart disease, and more.

    This isn’t just theory, you’ll work in cutting-edge labs, run experiments, and dig into current research that shapes medicine today. With this major, you can help to solve tomorrow’s big health problems, from metabolic disorders to signalling errors. It’s science with purpose.

    Career opportunities

    When you major in Molecular Basis of Health and Disease, you open doors to a wealth of meaningful careers. A significant number of our BBiomedSc graduates are successful in obtaining PhD positions or gaining postgraduate entry into professional health programmes such as Dentistry, Medicine, and Pharmacy.

    Here are just a few paths you could follow:

    • Research scientist in biotech or academia
    • Biomedical or pharmaceutical industry roles
    • Diagnostic or clinical lab specialist
    • Policy, technical or regulatory advisor in government or NGOs

    How you will learn

    In this major, you don’t just read about molecules, you study them in action. You’ll engage in lectures, tutorials, and hands-on laboratory work, where you learn experimental techniques, analyse real data, and think like a scientist. At Otago, many of your classes are informed by current research, so you’re not just learning what’s been discovered but you’re also learning how to make new discoveries.

    You’ll also work alongside expert researchers and peers who are as passionate as you are. This builds a sense of community and shared purpose, and gives you a taste of what a future research career could look like.

    Recommended high school subjects for undergraduate study

    To thrive in this major, it helps if you enjoy biology and chemistry, feel curious about how cells and molecules work, and like getting hands on in the lab. Strong analytical and problem-solving skills make a real difference too. High school chemistry is strongly recommended.
