Postdoctoral researchers, often referred to as postdocs, are individuals who have completed their doctoral studies and are engaged in further academic research. They typically work under the supervision of a senior researcher or faculty member in a specific field, contributing to ongoing projects and developing their own research skills. This position allows them to gain additional experience and expertise, often leading to a more competitive edge in the job market. Postdoctoral positions are common in various fields, including science, engineering, and humanities. These roles can last from one to several years, depending on the project and funding availability. Postdocs often publish their findings in academic journals, collaborate with other researchers, and may also teach or mentor students.
