Principal Investigator
The lead researcher on an academic grant, responsible for directing the research, managing the budget, and supervising the team.
The Principal Investigator (PI) is the senior researcher who leads a funded research project, bearing responsibility for scientific direction, budget management, personnel supervision, and regulatory compliance. PIs are typically tenured or tenure-track professors, though some institutions allow senior research staff to serve as PI. Managing a research lab as PI involves balancing scientific vision with administrative duties, mentoring graduate students and postdocs, writing publications, and continuously seeking new funding. In STEM fields, maintaining an active, funded lab is essential for career advancement.
