Discrete Mathematics and Algorithms Research

The Department has a strong faculty working in various topics in discrete mathematics, especially algorithmic aspects. The interface between Theoretical Computer Science and Discrete Mathematics has been highlighted by recent EPSRC Reviews of both disciplines as being one of increasing importance. LSE is well placed to be at the forefront of future developments.

Individual faculty interests are listed below, along with our Postdocs and Research students.
