I have been at LSE since 1990, when I joined as a Lecturer in Mathematics. I recently finished a three-year term as head of the Mathematics department, during which time we embarked on some exciting developments in our degree offerings. In particular, at the undergraduate level, we expanded our BSc Mathematics and Economics programme and introduced a new undergraduate programme, the BSc Mathematics with Economics, which will begin in 2010.
The research activity in our department reflects to some extent its location in an institution that specialises in the social sciences. We are very active in discrete mathematics and the theory of computation (where my own interests lie), game theory, and financial mathematics, and we have related MSc programmes. LSE's distinctive social sciences focus is also apparent in our programmes. Students on both our undergraduate programmes will take core mathematics and economics courses that any degree in either subject must have, together with a range of courses in pure mathematics and in the types of applied mathematics useful for economic theory (eg game theory, and mathematics of finance, rather than 'physical' applied mathematics, such as mechanics). They will also study courses in the types of economics of most interest to students with a mathematical leaning. The new Mathematics with Economics degree is distinguished from the existing Mathematics and Economics degree in that approximately three-quarters of the courses taken are mathematics courses, whereas the 'and' degree comprises roughly equal amounts of mathematics and economics. Both programmes provide the opportunity to take courses in areas other than mathematics and economics.
Our undergraduate students come from all over the world, and they go on to great careers afterwards. Some enjoy both mathematics and economics already, while some have not previously taken any economics, but are enthusiastic to study it. The key ingredients to success in our programmes are very strong mathematical ability and a keen interest in both mathematics and economics.
