I am currently a Research Associate in Cardiff University. My research is supported by the EPSRC grant QUEST: Quantitative Estimates in Spectral Theory and Their Complexity (see https://cardiffquest.wordpress.com/ ).

I am generally interested in the spectral theory of non-selfadjoint operators. And the approximation of spectra. Past projects involved pseudospectra of non-normal Schrödinger Operators and more general resolvent norm estimates of partial Differential operators. For more information, see my personal website.


I am delighted about my recent Marie Skłodowska Curie success for the project “Computational Complexity in Quantum Mechanics” (COCONUT): https://www.cardiff.ac.uk/news/view/1762984-marie-skodowska-curie-fellowship
