B.A. Honors Botany: Biological and Biomedical Sciences

What is Botany?
Botany is the scientific study of plants. These studies are pursued in the field, in the botanic garden and in laboratories. Plants range from the largest forest trees to single celled algae of fresh and marine waters. The study of plants is of vital importance; they are the source of the food we eat, the oxygen we breathe, most of the medicines we use, and are core to the understanding of the processes of global climate change. Dealing with the threats from global climate change will be one of the biggest challenges of this century. Human manipulation of plants in the future will need to provide food and energy for an expanding human population, whilst conserving the biodiversity of living organisms and integrity of habitats.

Botany: The course for you?
If you are interested in the future of the planet and life on it then Botany is for you. Almost no other course offers you the opportunity to study the natural, living World in the field and laboratory. Our graduates enter into a large range of careers and, as there is a global shortage of plant scientists find employment in a huge range of careers.

Botany at Trinity
Trinity’s Botany course is unique in content in Ireland and uncommon in a European context. Uniquely, we integrate small-group teaching, field-based activities and the laboratory. Field-based teaching in ecology, physiology and plant evolution is at its heart: We consider both the whole plant and how it works in a natural context. All staff are research active with high profile, strong research interests in Ireland and the tropics. Consistently, our graduates have rated our course very highly indeed: we believe that our course offers you the best possible training in Ireland for your future career.

Graduate skills and career opportunities
When you graduate you can move directly into a career related to plant biology, such as nature conservation, environmental consultancy, environmental protection, plant evolutionary biology or agricultural research as well as teaching at second level. Our recent graduates are employed in many organisations, including Teagasc, the OPW, Botanic Gardens at Glasnevin, Kew, Edinburgh, Oman and Missouri, Barclay Crop Protection and the UK Carbon Capture and Storage Research Centre. Alternatively, you might decide to go on to take a higher degree in Trinity or elsewhere. The skills you acquire in the third and fourth years are also widely applicable in business and industry.

Your degree and what you’ll study
Trinity specialises in the study of the evolution and conservation of all forms of plant life and their response to global climate change impacts.

Courses include:

Plant biodiversity and conservation, Ecology, Plant physiology and global climate change, Long-term environmental change, Plant molecular biology, Pollination biology, Soil Science, Economic Botany.

The laboratories and greenhouses on Trinity campus, the Trinity Botanic Garden and the internationally recognised Herbarium support teaching. All courses are derived from active research lines and emphasis is placed on your own Capstone research project in the fourth year.

Job Opportunity Potential

If you are an international student studying at Trinity, you might be considering internship and graduate work in Ireland, in your home country, or elsewhere. This section provides information for Non EU students on working in Ireland during and after your studies. For information and resources to support an international job search, see our Devex resource which includes international job search advice and information.

Employers value candidates who have more to offer than a good degree with high grades. They look for students who are well rounded and who have experience outside the classroom. Search for and take advantage of opportunities to gain experience, develop your skill set, and gain a clearer picture of what you like and don't like in terms of career options.

For example, you can get involved in some of the many student clubs and societies in college, volunteer or get a part time job. Remember that voluntary work is as valuable as paid work on your CV or resume - it's a great way to demonstrate your skills to future employers. Have a look at the TCD Civic Engagement website and check out volunteering opportunities in Ireland and abroad.
