Postgraduate research represents a formal area of study that is recognized by a university or institute of higher learning. The notion of "postgraduate" refers to studies following a undergraduate degree. Postgraduate research either occurs within a postgraduate degree that also includes taught elements, such as the thesis completed after the all but dissertation stage of an American-style Doctor of Philosophy (PhD) degree, or refers to research degrees common in Commonwealth countries such as a masters by research or British-style doctorate.[1]
