I have been at the LSE for more than 20 years. During that period I taught from large undergraduate calculus courses to specialised PhD courses. I've also undertaken more administrative and supportive roles such as Departmental Tutor and MSc Programme Director. Working with students is one of the most inspiring and satisfying aspects of working at the LSE. I am currently the Head of Department for the Department of Mathematics at LSE.
My research interests are in discrete mathematics in general, with the focus on graph theory. I am interested in structural properties of classes of graphs (such as planar graphs) and algorithmic aspects of properties of graphs in those classes. I've also published in related areas such as matroid theory.
Although I like to work on problems that are inspired by real-life applications; my research is in general of a pure and abstract nature.
My list of publications can be found via my personal website www.maths.lse.ac.uk/Personal/jan/publications.html, and also on Google Scholar.
