There is a vacancy for a postdoc position in topology at our department in Utrecht. The position is for two or three years, and is funded by the Dutch science organisation NWO. It is part of a specific research project, which in practice means that we are looking for candidates working in the convex hull of stable homotopy theory -- topological field theory -- operads -- higher categories. The starting time is flexible, although we aim to fill the position between 1 August 2009 and 1 January 2010. If you're interested, please send me an email and append your CV.
