What is a physics postdoc?

A Physics Postdoc, or postdoctoral researcher in physics, is an individual who has completed their Ph.D. in physics and is engaged in further research, typically at a university or research institute. Postdocs work under the supervision of a principal investigator and contribute to ongoing projects, often publishing their findings in scientific journals. The role is intended to provide advanced training and experience, preparing postdocs for independent research careers, academia, or industry positions. Physics postdoc positions are usually temporary, lasting from one to three years.
