Mariana Chatzakou is a postdoctoral researcher at Ghent University. She obtained her PhD in mathematics in 2020 at Imperial College London. Her research interests concern the areas of harmonic analysis, non-commutative analysis, pseudo-differential operators, functional inequalities on Lie groups, and PDEs with very strong singularities.Michael Ruzhansky is a Senior Full Professor of Mathematics at Ghent University in Belgium, and a Professor of Mathematics at Queen Mary University of London in the United Kingdom. His research interests mainly lie in Partial Differential Equations, Microlocal and Harmonic Analysis, and Pseudo-Differential Operators on Lie Groups and Manifolds. Previously, he had appointments at Utrecht University, Johns Hopkins University, University of Edinburgh, and Imperial College London. He is the recipient of various awards and fellowships, notably, the Ferran Sunyer i Balaguer Prize in 2014 and 2018, Daiwa Adrian Prize in 2010, and the ISAAC award in 2007. He is serving as the head of the Ghent Analysis & PDE Center of Ghent University. Diana Stoeva is a senior postdoctoral researcher at the University of Vienna. She obtained her PhD in mathematics in 2006 at the Higher Attestation Commission of Bulgaria and her Habilitation at the University of Architecture, Civil Engineering and Geodesy in Bulgaria. Her research interests lie in functional analysis, geometry of Banach spaces, frame theory, operator theory, and Gabor and wavelet theory.
