What Is Life Science?
Life science is the branch of natural science that studies living organisms, including plants, animals, microbes and humans. It spans sub-disciplines such as biology, zoology, botany, biochemistry, microbiology and biotechnology. Sitting alongside physical science within natural science, it explores how life works at molecular, cellular, organism and ecosystem levels.
Life science, also called the biological sciences, is the study of living things. It covers everything from single-celled bacteria to plants, animals and the human body. As one of the two main branches of natural science, it complements physical science, which deals with non-living matter such as physics and chemistry.
It is a very broad field with many sub-disciplines. Some focus on specific groups of organisms, such as zoology for animals or botany for plants. Others focus on specific systems or scales, such as neuroscience for the nervous system, genetics for heredity, or molecular biology for the chemistry inside cells.
Bachelor of Science (BSc): Courses and ScopeRead →What Is the Scope of a Life Science Career?
Life science offers a broad scope across healthcare, pharmaceuticals, biotechnology, food and agriculture, environmental consultancy, cosmetics and non-profit research. Graduates work in laboratories, universities, hospitals, drug-manufacturing firms and government agencies. Beyond research, careers also open in administration, management, sales, scientific writing and regulatory affairs, giving science graduates flexible, wide-ranging options.
Because life science underpins medicine, food, agriculture and the environment, its graduates are employed across many sectors. Common employers include pharmaceutical and biotechnology companies, hospitals and diagnostic labs, healthcare providers, food-processing firms, cosmetic manufacturers, environmental consultancies, research institutes, universities and government or non-profit organisations.
A science background also supports roles beyond the lab bench. Many graduates move into administration, project management, sales, technical writing, legal and regulatory support, and science communication, where subject knowledge is valued alongside professional skills.
Biotechnology Scope and OpportunitiesRead →Which Are the Top Life Science Jobs?
Popular life science jobs include biomedical scientist, biotechnologist, biochemist, microbiologist, computational biologist, bioinformatician, clinical research associate, industrial pharmacist and research assistant. These roles span diagnostics, drug discovery, genetics, data analysis and quality trials. Most require a relevant bachelor's or master's degree, and research-led positions often expect a PhD.
- Biomedical scientist: tests patient samples such as blood and tissue to help doctors diagnose, treat and prevent disease, drawing on pathology, physiology and anatomy.
- Biotechnologist: combines biology with technology to develop new products in pharmaceuticals, healthcare, agriculture, chemicals, environmental protection and food production.
- Biochemist: studies the chemistry of life, examining molecular structures to solve biological problems and develop new products and processes for food and agriculture.
- Computational biologist: applies mathematics, computer science, statistics and data analysis to biological systems, spanning genomics, molecular biology, ecology and neuroscience.
- Microbiologist: studies microorganisms and their biology to solve problems in medicine, pharmaceuticals, industry and environmental protection.
- Clinical research associate: organises and runs trials to test the safety and effectiveness of new medicines at approved study sites.
- Industrial pharmacist: works on the discovery, development, production and marketing of safe and effective medicines and drugs.
- Bioinformatician: builds methods and software tools that combine statistics, computing, mathematics and engineering to analyse biological data.
- Research assistant: supports academic research within an institution, often as a graduate step before or during postgraduate study.
What Are the Main Life Science Career Areas?
Life science careers fall into three broad areas: academia, non-academic research and industry. Academia includes professors, lecturers and department heads. Non-academic paths cover staff scientists, senior researchers, lab managers and research technicians. Industry roles range from research scientists to chief scientific officer, director and vice-president level leadership positions.
- Academia: department head, professor, associate professor, assistant professor and college lecturer.
- Non-academic research: senior researcher, government scientist, staff scientist, laboratory manager and research technician.
- Industry: vice-president, chief scientific officer, director, manager and senior researcher.
How Much Do Life Science Jobs Pay?
Pay varies by role, country and experience. In the UK, National Careers Service lists microbiologists at 23,000 to 45,000 pounds, biomedical scientists at 30,000 to 53,000 pounds, and biotechnologists at 27,000 to 57,000 pounds a year. Research scientists earn 27,000 to 48,000 pounds. Salaries rise with a master's or PhD.
