Postdoctoral researchers, often called postdocs, are individuals who have completed their doctoral studies and are engaged in further academic research. They typically work under the guidance of a senior researcher or faculty member in a university or research institution. This position allows them to deepen their expertise in a specific field and contribute to ongoing research projects. Postdocs usually hold temporary positions that last from one to several years. They are involved in various tasks, including conducting experiments, publishing research findings, and mentoring graduate students. This experience is crucial for those aiming to secure permanent academic or research positions in the future.
