Principal Investigator Eligibility & Responsibilities

Revised Human Subjects Regulations (Common Rule) Wednesday, June 20th 2018

The regulations that human subjects researchers must adhere to (referred to as the Common Rule Regulations) were established in 1991. In 2011, federal agencies began the long-awaited process to revise these regulations and, on January 18, 2017, the final revisions to the Common Rule (Final Rule) were posted in the federal register. The effective and implementation dates have recently changed. As posted in the federal register on June 18, 2018, the revised final Common Rule is both effective and to be implemented on January 21, 2019 with the option of implementing 3 burden-reducing provisions before January 21, 2019.

Principal Investigator (PI) Definition

Conducting research with humans is a privilege and carries with it ethical and legal responsibilities. By Colorado State University (CSU) policy and federal regulations, the Principal Investigator (PI) is the individual responsible for writing an accurate proposal to utilize human subjects, and for designing practices and implementing the approved use(s) of those subjects. Ultimately, the PI assumes the responsibility for the ethical conduct of the project and for the welfare of the human subjects. The PI should understand and abide by all relevant federal regulations and guidelines for the use of humans in research.
