A Postdoctoral Fellowship is a temporary research position for individuals who have completed their doctoral studies, typically a Ph.D. These fellowships allow researchers to deepen their expertise in a specific area, often working on advanced projects under the guidance of experienced mentors. They are common in fields like science, engineering, and humanities. Postdoctoral fellows usually engage in independent research, publish their findings, and may also teach or supervise students. These positions are crucial for career development, as they help build a professional network and enhance qualifications for future academic or industry roles.
