Why study natural and biological sciences abroad?
Studying abroad allows you to explore unique ecosystems, access cutting-edge research facilities and learn from leaders in the field. Many universities offer strong links to research institutes, conservation groups and environmental agencies.
You’ll take part in lab experiments, field studies and collaborative projects. Some programs include international research trips or placements, giving you a global perspective on science and conservation.
During your studies, you’ll develop key skills in observation, problem-solving, data analysis and scientific writing. These are valuable in a wide range of science and technology careers.
A science degree from a respected international university can also lead to further research or academic study, as well as career opportunities in your host country or around the world.
Types of natural and biological sciences programs
There are many degrees available to match your interests, from lab-based research to outdoor fieldwork.
Biology
Biology degrees explore the structure, function, growth and evolution of living organisms.
Courses cover topics like genetics, cell biology, microbiology and ecology. Many programs offer lab work and field courses. You could study:
- General Biology
- Molecular Biology
- Marine Biology
- Ecology and Evolution
Environmental science
These programs focus on the relationship between humans and the natural world. You’ll study climate change, conservation, sustainability and ecosystems. Degrees often include outdoor research and environmental policy. Common options include:
- Environmental Science
- Climate and Sustainability Studies
- Conservation Biology
- Earth and Environmental Systems
Chemistry
Chemistry programs focus on the structure and reactions of matter. You’ll learn about organic, inorganic and physical chemistry, often through lab-based work. Chemistry is also key for future study in medicine or environmental science. You might study:
- General Chemistry
- Medicinal Chemistry
- Environmental Chemistry
- Chemical Engineering
Physics and earth sciences
These degrees explore forces, energy, matter and planetary systems. You’ll gain a deep understanding of the natural laws that shape our universe. Programs often combine theory with practical research. Options include:
- Physics
- Geology
- Astronomy
- Oceanography
Careers in natural and biological sciences
Science graduates are in demand in many fields, including research, conservation, education, public policy and industry. You might work in a lab, on a research vessel, in a national park or in a policy office.
Biology and environmental science graduates often work in conservation, ecology, sustainability or biotechnology. Chemistry graduates may work in pharmaceuticals, food science or environmental testing. Earth science and physics graduates are well suited for careers in engineering, renewable energy or meteorology.
Many students go on to postgraduate study or research. With experience, you can specialise further or move into leadership roles.
