Autorenporträt

Vishvesh Kumar earned his Ph.D. in Mathematics from the Indian Institute of Technology Delhi, India, in 2019. Currently, he is a postdoctoral researcher at the Ghent Analysis & PDE Center, Ghent University, Belgium. His research focuses on pseudo-differential operators, abstract harmonic analysis, and partial-differential equations on Lie groups and symmetric spaces. He has authored over 40 research articles published in several leading international journals. He is a life member of the International Society for Analysis, its Applications, and Computation (ISAAC). David Rottensteiner earned his PhD from Imperial College London in 2014. Since then he has held postdoctoral positions at the University of Vienna, Austria, and Ghent University, Belgium. His research focuses on harmonic analysis and pseudo-differential operators on nilpotent Lie groups.  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.
