Principal Investigator
Principal investigator (pronunciation: prin-suh-puhl in-ves-ti-gey-ter) is a term used in research and academia to denote the individual who is responsible for the design, conduct, and reporting of a research study or experiment. The term is most commonly used in the context of grant funding to refer to the person who is in charge of a funded project.
Etymology
The term "principal investigator" is derived from the Latin words "princeps" meaning "first" or "chief" and "investigare" meaning "to trace out" or "to search". The term thus refers to the person who is primarily responsible for carrying out an investigation or research project.

This includes the design of the study, the collection and analysis of data, the interpretation of the results, and the reporting of the findings.
