Study Coordinators, who are often but not always nurses, are the “experts” of the protocol aside from the Principal Investigator. They have a high level of expertise and devote a great deal of time to the planning and conduct of a research project. They will assist you throughout the study during the consenting process, taking the study medication, performing evaluations, and answering any questions you may have. An experienced Study Coordinator is a valuable source of knowledge and guidance for patients.
