Background

I am Director of Pure Mathematics in the School of Mathematics, Statistics and Physics, and I co-chair the School's EDI Committee. I am a member of the London Mathematical Society and the European Mathematical Society, and I have been a Fellow of the UK Higher Education Academy (Advance HE) since 2017. From 2019 to 2024 I represented the UK on the managing committee of an EU-funded project on Mathematical Models for Interacting Dynamics on Networks (COST Action 18232).

Before arriving in Newcastle I was at the University of Oxford, most recently as a fellow of St John's College, and before that as an undergraduate and later graduate student at Hertford College and Balliol College, respectively. I completed my Habilitation at TU Dresden, Germany.

Research

My area of research is operator theory, and I am particularly interested in the quantitative asymptotic behaviour of operator semigroups. My work combines elements of functional analysis, harmonic analysis and complex analysis, and it has applications in the study of energy decay of damped waves, in some areas of mathematical control theory and in the theory of iterative methods.

I recently co-organised the conference New Challenges in Operator Semigroups, which was held in St John's College, Oxford.

My work has received generous financial support from various sources, including the London Mathematical Society, the Heilbronn Institute for Mathematical Research, the Engineering and Physical Sciences Research Council and the European Cooperation in Science and Technology (COST).

I welcome enquiries from prospective Master's students, PhD students and postdocs in my area of expertise.
