Staff Profile

Dr David Seifert

NUAcT Fellow in Pure Mathematics


I joined Newcastle University in September 2019 as a member of the Pure Mathematics group in the School of Mathematics, Statistics and Physics. I currently organise the Pure Mathematics group's Analysis Seminar, and I am a member of the School's EDI Committee. Together with Dr Chris Harrison I oversee the School's new mentoring scheme for postgraduate research students. I also 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.

Before coming to Newcastle I was a member of the University of Oxford, most recently as a postdoctoral 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, in November 2020.


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.

I am always happy to hear from prospective Master's or PhD students who would like to work with me.
