En projektledare är huvudforskare eller upphovsperson till ett särskilt väldefinierat vetenskapligt projekt (eller annat forskningsprojekt), som en labratorieundersökning eller klinisk prövning. Används ofta som en synonym för ”laboratoriechef".

A principal investigator (PI) is the lead scientist or engineer for a particular well-defined science (or other research) project, such as a laboratory study or clinical trial. It is often used as a synonym for "head of the laboratory," not just for a particular study. In the context of USA federal funding from agencies such as the NIH or the NSF, the PI is the person who takes direct responsibility for completion of a funded project, directing the research and reporting directly to the funding agency.[1] For small projects (which might involve 1-5 people) the PI is typically the person who conceived of the investigation, but for larger projects the PI may be selected by a team to obtain the best strategic advantage for the project. In the context of a clinical trial a PI may be an academic working with grants from NIH or other funding agencies, or may be effectively a contractor for a pharmaceutical company working on testing the safety and efficacy of new medicines.
