Who typically holds the title of Principal Investigator in a research study?

The title of Principal Investigator (PI) is typically held by the individual who is primarily responsible for the design, conduct, and management of a research study. This person is usually a senior scientist or faculty member with the expertise relevant to the research field and is accountable for the integrity and ethical conduct of the study, ensuring compliance with regulatory and institutional policies, including those set by the Institutional Animal Care and Use Committee (IACUC).

The PI plays a crucial role in obtaining funding, overseeing research staff, and ensuring that the study adheres to approved protocols and ethical standards. In contrast, the other roles, such as Lead Research Technician, Study Coordinator, and Project Manager, while important in supporting the research process, do not carry the same level of responsibility and oversight typically associated with the Principal Investigator title.
