What is Genetics?

Genetics is the study of genes, genomes and heredity.

Is this the right course for you?

If you are interested in understanding the principles of inheritance; how genetic mechanisms control different developmental and physiological processes in biology; and how a perturbation of these mechanisms leads to disorders and diseases, this is the right course for you.

Why study Genetics at Trinity?

The Department of Genetics at Trinity is housed in the Smurfit Institute. There are 14 members of faculty and a number of academic associates, working in a wide range of areas of genetics covering everything from medical genetics to evolutionary genetics. The Department of Genetics at Trinity has an international reputation for high-quality research and more than 50 years of experience in teaching genetics to undergraduate students. Our teaching is research-driven, meaning that undergraduate students are instructed by active research scientists with excellent track-records.

What will you study?

During the Junior Sophister (third) year, students will learn about the fundamentals of genetics through a combination of lecture courses and practical classes. To this end, students will be exposed to different areas of genetics ranging from bacterial genetics, to plant genetics, to medical genetics. Practical classes teach the students about key techniques and analysis methods that are widely used in genetics laboratories. In the Senior Sophister (fourth) year, students can choose, largely depending on their interests, from a number of lecture courses on different areas of genetics. They also spend 10 to 12 weeks in a laboratory of the institute and participate in ongoing research projects. They further write an in-depth literature review on a current topic of genetics.


Bacterial Genetics, Eukaryotic Molecular Genetics, Genomics, Neurogenetics and Drosophila, Medical Genetics, Evolutionary Genetics, Molecular Genetics Laboratory, Analytical Genetics Laboratory, Data Handling, Genetics tutorials, Review (Genetics), Broad Curriculum (see


Literature review, Research project, Medical and Cellular Genetics (which contains the following courses: Cancer Genetics, Transgenic Animals and Gene Therapy, Genetics of Perception, Prion-Like Proteins, Apoptosis, Stem Cell Biology, Plant Developmental Genetics), Analytical and Molecular Genetics (which contains the following courses: Genetics and Immunology of Neural Diseases, Molecular Evolution II, Microbial Molecular Genetics, Plant Molecular Genetics II, Developmental Genetics of Drosophila, Human Evolutionary Genetics, Genetics of Neural Development, Behavioural Genetics, Epigenetics).


The Department helps students to secure internships in research laboratories (both in Ireland and abroad) over the summer in-between the third and fourth years so that they can gain valuable research experience.


Many genetics graduates go on to higher degrees (M.Sc. and/or Ph.D.) and take up careers in research in either academia or industry (especially in the biotechnology or pharmaceutical sector). Other students go on to medical school and become physicians, or they become science teachers or genetic counsellors, or are employed in a wide range of other professions.

Graduate Profile

Bennett Thomson

Applying for Genetics at Trinity has been one of the best decisions I have made to prepare me for a future in science.

Not only has specialising in Genetics allowed me to learn about a diverse range of topics taught by enthusiastic, research-focused lecturers at the forefront of their fields, the extensive practical modules have also offered invaluable experience in developing essential laboratory skills.

The Smurfit Institute of Genetics has an international reputation for high-quality research, and having the opportunity to study in an environment that cultivates scientific excellence has been paramount in equipping me with the necessary skills to pursue a career in research.

Student Profile

Róisín-Ana Ní Chárthaigh

Studying Natural Sciences at TCD was the ideal course for me; the Freshman (first and second) years allowed me to see what areas of science fascinated me most! In the Sophister (third and fourth) years, knowledge of other areas of science was helpful. Positive experiences of past students I spoke to and TCD's reputation for world-class research also influenced my choice.

I'm currently a fourth year Genetics student. The course teaches both the core, classical genetics, and illuminates the field frontiers, through lab practicals and in-depth lectures. The assignments and projects encourage students to pursue those areas of genetics of greatest interest to them, and to develop the ability to think independently and critically.

I'd recommend organising practical experience for yourself, no matter what area of science you study. I spent the summer of my third year in a retinal genetics lab in Paris, fusing science, culture and sunshine! It's a great gauge to see if you'd like to work in that field, and helps in your final year project.

This course has given me a passion for genetics; I hope to go on to a PhD.
