I studied at University of Galway (then UCG) from 1988 to 1993 obtaining a B.Sc (Mathematics) and an M.Sc. (Mathematics). Following that I obtained my PhD from University of Alberta, Canada in 1999 under the supervision of Prof George Peschke. After a period teaching at University College Cork, I have been a lecturer at University of Galway since September 2001

Discrete Geometry: Most of my research focuses on the problems that involve some combinatoricial aspect (e.g. graphs, simplicial complexes, finite groups) and some geomtric or topological aspect (rigidity of structures, embeddings in surfaces). I am particularly interested in graph rigidity

I have taught a wide range of courses during my career across all aspects of the undergraduate mathematics syllabus. I have also taught courses in computer science and in actuarial science.
