Chief Investigators

Members of our Chief Investigator Scheme

POMCTN aspires to nurture and support interested clinicians with experience in research at a local level, to progress to become grant co-applicants, members of trial clinical investigator groups and ultimately Chief Investigators.

As such we have set up our Chief Investigator Scheme to develop and mentor the CIs of tomorrow.

Current CI Scheme members were recruited through open competition in 2017 and 2018. All recruitment rounds are advertised on this website, our newsletter and on our Twitter feed.

Those wishing to register an interest in the Chief Investigator Scheme should contact us.
