Staff Profile

Dr David Seifert

NUAcT Fellow in Pure Mathematics

Background

I joined Newcastle University in September 2019. I am a member of the Pure Mathematics group in the School of Mathematics, Statistics and Physics. Before coming to Newcastle I was in Oxford, most recently as a fellow of St John's College, and before that as a student at Hertford and Balliol Colleges.

I am a member of the School's EDI Committee, and I represent the UK on the managing committee of an EU-funded project on Mathematical Models for Interacting Dynamics on Networks (COST Action 18232). I have been a Fellow of the UK Higher Education Academy (Advance HE) since 2017.

Research

My research interests lie in operator theory and its applications to linear evolution equations. 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.
