Recent Surveys in universities world wide where professors are required to teach, conduct research, and provide services to the university and link with the industry, indicated that professors spend little time on research. Teaching, research supervision and “management and organisational tasks” were all bigger commitments. Associate and assistant professors are little better carving out research time for themselves.
Therefore, if your are a full professor who love research, working in academia may your best choice. It may be easier to pursue your intellectual interests outside the university system. what do you think?
