Mathematics is a living subject with new processes, techniques and theories constantly being devised, tested and explored. The extensive use of computers in a wide range of academic areas has led to an increasing demand for statistical and mathematical analysis in many new fields. Modern mathematicians and statisticians are being asked to develop new tools and techniques to deal with problems in areas from business management to biology. New insights are also being opened up in the more traditional areas of physical science and engineering. All this activity leads to new applications of mathematics and statistics, as well as new theoretical work on the structure of the mathematics involved. The Postgraduate Diploma in Science usually comprises four full-year courses or eight single-semester courses selected from a range of options.

Postgraduate study can bring many career benefits eg, specialist skills and enhanced knowledge, entry into specific occupations, higher starting salary/progression rates, research capability/achievement and evidence of high academic attainment/self-discipline.
