Medical physicists work in healthcare and use their knowledge of physics to develop new medical technologies and radiation-based treatments. For example, some develop better and safer radiation therapies for cancer patients. Others may develop more accurate imaging technologies that use various forms of radiant energy, such as magnetic resonance imaging (MRI) and ultrasound imaging.
A Ph.D. in physics, astronomy, or a related field is needed for jobs in research or academia or for independent research positions in industry. Graduate students usually concentrate in a subfield of physics or astronomy, such as condensed matter physics or cosmology.
Overall employment of physicists and astronomers is projected to grow 7 percent from 2019 to 2029, faster than the average for all occupations. Physicists are projected to have employment growth in the scientific research and development services, educational services, and healthcare and social assistance industries.
Physics research is usually done in small- or medium-sized laboratories. Although physics research may require extensive experimentation in laboratories, physicists still spend much of their time in offices, planning, analyzing, fundraising, and reporting on research.
