Professor

Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, professor derives from Latin as a person who professes. Professors are usually experts in their field and teachers of the highest rank.In many systems of academic ranks, professor refers only to the most senior academic position, sometimes informally known as full professor. In some countries and institutions, the word professor is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States. This colloquial usage would be considered incorrect among other academic communities. However, the unqualified title Professor designated with a capital letter nearly always refers to a full professor.Professors often conduct original research and commonly teach undergraduate, professional, or postgraduate courses in their fields of expertise. In universities with graduate schools, professors may mentor and supervise graduate students conducting research for a thesis or dissertation. In many universities, full professors take on senior managerial roles such as leading departments, research teams and institutes, and filling roles such as president, principal or vice-chancellor. The role of professor may be more public-facing than that of more junior staff, and professors are expected to be national or international leaders in their field of expertise.
