I have a Ph.D in History and have work experience as a Postdoctoral Fellow. I did little teaching; mostly research, organising Conferences etc. Should I choose the NOC Code 4011 for University Professors (which includes the job title Postdoctoral Fellow) or 4169 (Other professional occupations in social science, n.e.c which includes historian). What sort of job duties should I write, will one sentence (as in the 4169 NOC description) that I conducted historical research and another naming the field of research do?
