Why is this course for me?

Microbiology is the study of microscopic organisms known as micro-organisms or microbes. Microbes play a key role in every facet of life on this planet. For example, microbes have a major impact on the earth’s climate by their metabolism of greenhouse gases like carbon dioxide and methane. Microbes can naturally produce polymers, antibiotics but also consume or break down a multitude of toxic chemicals. Microbiologists use tools like molecular biology, fermentation, enzymology and synthetic biology to improve the natural ability of microorganisms so that they can produce new antibiotics, natural products, biodegradable plastics and clean up chemically polluted soil and water. Microbes protect us from colonisation by disease-causing organisms. However, some microbes cause disease, e.g. MRSA, AIDS, tuberculosis and meningitis. Microbiological research aims to find treatments for these and other infectious diseases.

Career & Graduate Study Opportunities

Microbiologists are employed in the healthcare, pharmaceutical and food-related industries, hospitals and veterinary hospitals and related laboratories. They also find work in government agencies such as the Environmental Protection Agency where they are involved in research and development, process design and control, management and quality control. Many students opt to continue their undergraduate degree with an MSc or PhD graduate programme. These microbiologists play a key role in developing new drugs, finding novel ways to combat infectious diseases and designing new approaches to clean the environment and develop a green economy.

What Will I Study

This is a sample pathway for a degree in Microbiology. Topics include biotechnology, microbes and the environment, medical microbiology and pharmaceutical microbiology.

First Year

  • Biology
  • Chemistry
  • Mathematics
  • Optional Science modules
  • Elective module

Second Year

  • Microbiology
  • + 2 Other Science Subjects
  • Elective modules

Third Year

  • Microbiology
  • Optional Science modules
  • Elective modules

Fourth Year

  • Microbiology (includes a research project)

Timetables & Assessment

Each student will have their own timetable based on their individual module selection. This is a full time course and classes may include lectures, practicals and tutorials, depending on the subjects. Students will also be expected to study independently (autonomous student learning). Assessment varies with each module but may comprise continuous assessment of practicals, written exams and online learning activities.

Professional Work Experience
Students carry out a research project in fourth year that can take place in a pharmaceutical or food-related company or a hospital. Recent placements include Alltech, APC, Pfizer, Monaghan Biosciences and the HSE Public Analyst’s Laboratory.

International Study Opportunities

A limited number of fourth year projects are available in the Faculty of Pharmaceutical Sciences of the University of Copenhagen, Denmark.


“DN200 was the perfect choice for me. This gave me the opportunity to try out a variety of subjects, including Neuroscience, Biochemistry and even Physics, before deciding on my favourite – Microbiology. I am currently working as a QA Food Science associate in a Glanbia dairy and am involved in assurance of the quality of milk from raw milk intake to final product despatch. My analytical style of thinking developed throughout my degree with UCD is vital for my role, working with large sets of data. The programme is two years in length with a rotation for the second year either in a new role or to a new geographical location or both. I would love the opportunity to try R&D as part of my rotation, something different but I’m sure equally as challenging as quality assurance.”
