Tropical ecosystems provide important resources locally and globally, and coral reefs are the most diverse of marine ecosystems threatened by human activities.
An Integrated PhD provides a route into research study if you do not have a master’s degree, or have very little research training. It enables you to spend your first year completing a full-time Masters-level qualification, followed by a full-time PhD studied over 3-4 years or a part-time PhD studied over 6-7 years. We also offer a ‘standard’ PhD in this subject which can be studied either full-time (3-4 years) or part-time (6-7 years).
The first year on our Integrated PhD Tropical Marine Biology, is designed to deliver advanced tropical marine biology theory and to facilitate the development of a comprehensive range of practical and professional skills required by today’s employers. As a student at our School of Life Sciences you will benefit from the breadth of research carried out by our internationally recognised academics and will engage with current research activities both in the UK and abroad. You also can put theory into practice and study coral reef conservation first-hand during the school’s annual field trip to the Wakatobi Marine National Park, Indonesia. Please note that students who join this optional expedition are subject to additional travel costs – the fee for field trips vary from year to year.
In your second year you move into the PhD element of the course. Research in our School covers a wide spectrum of biology from genes to ecosystems, and this broad-based structure provides opportunities for developing novel ideas and inter-disciplinary projects. We offer supervision in all areas of staff expertise in marine biology including community ecology of coral reef systems, tropical seagrass beds, mangroves and fisheries, deep sea/marine connectivity, ocean acidification and macronutrient cycling.
Your future
As the world's environmental problems increase, the demand for qualified marine biologists continues to grow, and postgraduate study is often a requirement for becoming a researcher, scientist, academic journal editor and to work in some public bodies or private companies.
Our graduates go on to a range of careers. Some choose to continue into a research career by taking up doctoral positions in the UK or overseas. Others work with governmental and non-governmental organisations and environmental agencies, consultancies, and voluntary organisations. We support your career development by a mentoring scheme and employability events.
