You may like to work on the 'Scope of Talent Management, its need, and approach to its implementation in mid size organizations'. Since there is a big gap in the formalized understanding of new terminologies like talent management, it may be worthwhile creating a standardized definition of 'talent management' after researching all available material on this subject and evolve a workable methodology which helps organizations to collect employee data & analyze the same in a manner as to identify the hidden 'talent' and groom it for individual & organization's growth.
In my opinion, it is a vast subject, which is somewhat controversial at present, since different HR experts have defined it differently, and there is no collective understanding about the technology dimension of an 'approach to talent identification & development'.
