About me

I am a Senior Lecturer (Associate Professor) in Mathematics, in the School of Mathematical and Statistical Sciences, at the University of Galway (formerly called NUI Galway). 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 University of Galway, and broader mathematical community, in various ways including, at present, 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 which was held here in Galway in June 2022.

For the Fall semester of 2023/2024, I am a visiting on sabbatical, and am a visiting scientist at the Department of Mathematics and Statistics, Memorial University, St. John's, Newfoundland.
