Typically, postdoctoral positions are full-time commitments. They are designed to provide extensive research experience and training in a specific field, which often requires a full-time presence in the lab or research environment. However, the possibility of part-time postdoc positions may vary depending on the institution, funding availability, and specific project requirements.
It is advisable to directly inquire with potential advisors or institutions about their policies regarding part-time postdoc opportunities.
