The LSE (London School of Economics) has advertised twenty new positions across all its departments (which include mathematics and statistics) and at all levels, from lecturer (=assistant professor) to professor (=full professor). See http://www.lseglobaldebate.com
The deadline is 7 December.
LSE, as a Social Sciences university, does not have a computer science department or departments in traditional sciences, but has active research groups in the areas of discrete mathematics and algorithms, game theory, financial mathematics, and many areas of statistics.
It’s an open recruitment exercise, in the sense that departments have not each been given fixed numbers of positions, but essentially will be in competition with each other for the positions. So it is a fairly unusual hiring exercise. When applying, candidates are asked to indicate which department they would want to belong to (and interdisciplinary will be likely to be viewed positively). If you might be interested in applying, with a view to joining the Mathematics department (and/or the Statistics department, with whom we work closely), and would like to discuss, please contact me (email@example.com) and/or the head of the Mathematics department, Jan van den Heuvel (firstname.lastname@example.org).
