About me

I am a lecturer at the University of Glasgow in both the Geometry and Topology group and the Algebra group. Prior to this I was a postdoc with Prof. Michael Weiss at the Westfaelische Wilhelms-Universitaet Muenster and a postdoc at the Max Planck Institute for Mathematics in Bonn. I completed my Ph.D. under the supervision of Prof. Andrew Ranicki at the University of Edinburgh. I am mostly interested in the following branches of mathematics: Geometric Topology, Algebraic Topology, Controlled Topology, Algebraic and Geometric Surgery theory and Algebraic K-Theory.

Research Interests

For X a (finite) simplicial complex that is homotopy equivalent to a manifold the topological surgery exact sequence of X can be identified with the algebraic surgery exact sequence of X. The latter sequence, due to Ranicki, is defined using simplicially controlled categories. I seek to generalise the algebraic subdivision functor defined in my Ph.D. thesis to the L-theory of simplicially controlled categories thereby defining a mapping of algebraic surgery exact sequences: ASES(X) --> ASES(X'). By subdividing sufficiently one can get arbitrarily fine control thus allowing one to map to a controlled version of the surgery exact sequence. This procedure is hoped to give rise to a 'controlled total surgery obstruction' analogous to Ranicki's algebraic total surgery obstruction.

Teaching

During my three years of teaching Mathematics at the University of Glasgow I have lectured the following courses:

I have also tutored the following courses:

I have supervised the following undergraduate projects:

I have been course head for 5M: Advanced Differential Geometry and Topology for the last three years and I have been course head for 2T: Topics in Discrete Maths for the last year.
