A clinical research coordinator (CRC) plays a crucial role in supporting and coordinating clinical trial activities under the direction of the principal investigator (PI). Their responsibilities span three stages: pre-trial preparations, during the trial, and post-trial closeout, which include obtaining informed consent, managing study documents, and ensuring compliance with protocols. The role of CRCs is increasingly in demand due to the growth of clinical research, with training opportunities available through organizations like CRB Tech Solutions.
