I am now using UR courses for my courses, you can log in by following the link below
I would really like to know more about the topology of singular spaces. A lot of the work
I have published up to now relates to Lusternik-Schnirelmann category and rational homotopy theory.
Recently Pascal Lambrechts and I have calculated the rational homotopy type of a configuration space of two points in a closed manifold and also of a blow-up of a manifold along a submanifold. A list of my publications is in my CV.
