Physicist

What does a physicist do?

• Develop theories and mathematical models to explain physical processes.
• Design and run experiments using specialist equipment and instruments.
• Write computer programs to simulate systems and analyse large datasets.
• Apply physics to develop new technologies, materials or products.
• Publish research papers and present findings at conferences.
• Write proposals to win funding or time at large research facilities.
• Work with engineers, computer scientists and other scientists on shared projects.

Where do they work?

Physicists work in universities, national and international research laboratories, government agencies, and companies in semiconductors, optics, energy, aerospace, defence, healthcare and technology. Most work involves computers, laboratories or both, and some projects need visits to large facilities such as particle accelerators, telescopes or reactors. Research often involves international teams. Early-career research posts are usually fixed-term, and many people move between countries for postdoctoral positions.

What skills do you need?

• Advanced mathematics
• Programming, for example in Python or C++
• Data analysis and statistics
• Experimental and measurement techniques
• Computer modelling and simulation
• Problem solving and abstract thinking
• Scientific writing and presentation

How do you become a physicist?

Start with a bachelor's or integrated master's degree in physics, which usually takes three to five years depending on the country. Strong mathematics is essential. For jobs with the title physicist, especially in research, a PhD is usually required, followed in universities by one or more postdoctoral posts. Many physics graduates instead use their skills in engineering, data science, software, finance or teaching. Summer research projects, programming experience and laboratory work help on every route. Graduates in mathematics, engineering or chemistry can move into physics through a master's.

1. Degree and PhD. A physics degree followed by a PhD is the standard route into research. A PhD takes about three to five years, depending on the country and whether a master's comes first. After that, most academic physicists do one or more fixed-term postdoctoral jobs before they compete for permanent posts.
2. Industry and applied physics. Graduates with a bachelor's or master's can work in applied roles in semiconductors, optics, energy, instrumentation, aerospace and defence. Some join as engineers or technical specialists. A master's in an applied area, such as photonics or materials, can help. A PhD is useful but not required for many industrial roles.
3. Related degree and master's. Graduates in mathematics, engineering, chemistry or computer science can move towards physics through a master's in physics or an applied field such as astrophysics, medical physics or materials science. This route works best if your first degree included a lot of mathematics and some physics.

Do you need a licence to work as a physicist?

Physics is not a regulated profession in most countries, and you do not need a licence to work as a physicist. Voluntary professional status, such as Chartered Physicist in the UK, can support your career. Some specialist roles are regulated. Medical physicists who work in hospitals usually need certification or registration, and people who work with radiation or nuclear material must follow strict safety rules and may need specific training. Check the requirements in your country.

How much does a physicist earn?

Earnings of Professionals around the world

Most countries do not publish pay for single job titles. The International Labour Organization collects median monthly earnings for broad occupation groups instead. This career belongs to ISCO-08 major group 2, "Professionals". The table covers the whole group, which includes physicist and many other occupations.

Career progression

1. Graduate physicist or research assistant
2. PhD researcher
3. Postdoctoral researcher or physicist
4. Senior scientist or lecturer
5. Principal scientist, research leader or professor

Job outlook

Physics skills are used in growing fields such as semiconductors, quantum technology, renewable energy, nuclear power, space and medical imaging. Permanent academic research posts are few and highly competitive, and research funding depends on government decisions. Many physics graduates find strong careers outside physics, because employers value their mathematical, programming and problem-solving skills. Those who build programming and data skills alongside physics usually have the widest choice.

Questions about becoming a physicist

What jobs can you get with a physics degree?

Physics graduates work as research scientists, engineers, data scientists, software developers, medical physicists, meteorologists, teachers and financial analysts. The degree develops strong mathematics, modelling and programming skills that employers in many sectors value. Only some graduates work with the title physicist, but many use physics every day in engineering, technology or data roles.

Do you need a PhD to be a physicist?

For research roles with the title physicist, a PhD is usually expected. With a bachelor's or master's, you can work in applied physics, engineering, technical or data roles, often doing similar work under a different job title. If you want to lead research in a university or national laboratory, plan for a PhD.

Is physics harder than engineering?

They are hard in different ways. Physics goes deeper into theory and mathematics and asks why things happen. Engineering applies physics to design things that work within cost and safety limits, with more practical projects. Many students find physics more abstract. Both need strong mathematics and a lot of practice.

Can physicists become engineers?

Yes. Many physics graduates work in engineering roles, especially in electronics, optics, aerospace, energy and instrumentation, where employers value their theory and modelling skills. To become a chartered or licensed engineer, you may need further study or extra experience, because professional bodies usually expect an accredited engineering degree or an equivalent.
