About me

I am a Senior Lecturer in Mathematics, in the School of Mathematical and Statistical Sciences, at the National University of Ireland Galway (NUIG). My research is in the area of numerical analysis, particularly finite element and finite difference methods for differential equations. My teaching covers a broad range of undergraduate and graduate modules in theoretical and computational mathematics. I contribute to the community at NUIG, and broader mathematical community, in various ways including, at present, as interim Head of Mathematics, as our school's director of Equality, Diversity and Inclusion, as an associate editor for Numerical Algorithms (Springer), and as one of the local of ILAS 2022: the 24th Conference of the International Linear Algebra Society here in Galway in June 2022 (postponed from 2020).
