A scientific research immunologist

Explanation:

A postdoctoral (commonly called postdoc) position is a temporary working position assigned by a particular institution/government agency to investigate questions referred to a particular research field/discipline (e.g., economy, molecular biology, immunology, politics, etc). In general, a postdoc is a 2-year position obtained after Ph.D. (i.e., Doctor of Philosophy) completion. This short-term research position is useful for professionals who require further training in a particular field/discipline, giving the individual more independence than in a Ph.D., which allows the development of technical skills and increases his/her interest in a particular research area.
