# Physics Major & Minor

The standard **Physics track** is excellent preparation for graduate school in physics, engineering, and closely related scientific fields. The Physics track is also designed to support the various options of the pre-engineering program and is excellent preparation for medical school.

The **Applied Physics track** is designed to prepare students for employment in industrial research and development laboratories, technical consulting firms, and technically oriented government agencies immediately upon graduation. The Applied Physics track is not recommended for those intending to pursue graduate degrees in either physics or engineering, but would be a good choice for students interested in patent law.

The **Biophysics track** is designed for students who are interested in Physics as a major and a career in the health professions. About one-quarter of Stetson physics graduates in the recent past have gone on to careers in health-related fields. Graduates have been accepted into graduate/professional programs in biophysics, medical physics, biomedical engineering and medical school. Other students have gone directly into the health-related workforce. The track features a course in biophysics taught by a research biophysicist and senior research capstone projects in biophysics are also available. The track closely follows the course requirements of the Stetson University pre-health program.

The Physics major (either the Physics track, Applied Physics track, or Biophysics track) is an outstanding liberal arts degree that develops critical thinking skills that are in high demand by employers in the private and public sectors. Graduates of the Physics Department work in a wide variety of careers, including faculty in universities, medical schools, and high schools; employed by companies such as IBM and Northrop-Grumman; and employed by government agencies such as the Department of Energy and NASA.
