I completed my PhD in Mathematics at the University of Pretoria in 1997. After teaching at the University of Pretoria and the University of South Africa, I spent two years in Germany at the Chemnitz University of Technology before coming to the LSE in 2009. I am interested in discrete, combinatorial and convex geometry, as well as geometric networks.
Combinatorial and discrete geometry;
convex geometry and the geometry of normed spaces;
shortest geometric networks
