ye.. thats a grt idea... may be 2121 would help... not sure though...he basically manage docs for patients enrolments for clinical Trials,data management and Clinical Research..He is in constant touch with docs & manages in his work!! But dint find this in any of the NOCs ..
My OH is a Mastres in Bio-Technology... He is majorly into Clinical research and lots of Job opps in canada for clinical research( we have done some survey, but unless we stay in Canada , it quite difficult to grab one from the UK) .... there are jobs in Canada for Clinical research, But I dont find it on NOC.. Quite Strange NOC!!!!

Reading 0311, the first duty "Plan, organize, direct, control and evaluate the delivery of health care services within a department or establishment" seems to make it clear to me that this NOC is for those involved in managing the delivery of healthcare directly, not clinical research.
I agree with jes_ON that 4165 seems like a better match, it seems to be the only NOC that even mentions clinical research.
