Launched in 2014, the Clinician-Investigator (CI) scheme is a research manpower development programme administered by the NHG Research & Development Office (RDO). The CI scheme is designed for established clinicians who wish to incorporate research into their clinical expertise with the aim of improving healthcare. The CI scheme also aims to promote a culture of collaborative research among established clinicians to generate better research outcomes and develop them as international Key Opinion Leaders (KOLs) in their respective research areas.
