Currently in charge of the group 


My research lies in analysis, more precisely operator theory and complex analysis. At the moment I am working with Nevanlinna functions and their generalisations to several variables, with focus on applications in electro engineering as well as with singular (differential) operators. Furthermore, I am continuing my studies on generalised Nevanlinna functions (functions that admit a realisation in a Pontryagin space). 
Permanent Staff 

Professor 
My main area of research is operator theory, in particular spectral theory and its applications to mathematical physics. My studies have roots in mathematical analysis, especially in the theory of analytic functions, but requires deep knowledge of modern physics. 
Senior lecturer 
My research interest concerns the interaction between operator algebras, group theory and representation theory. The major link between these topics is created by group operator algebras, such as the reduced group C*algebras or the group von Neumann algebra, both associated with an arbitrary locally compact group. Next to research mathematics, my professional interests include didactics of higher education and learning different languages. 
Senior lecturer 
My research interests are in harmonic analysis, pseudodifferential and Fourier integral operators, oscillatory integrals and multilinear versions thereof. 
Associate Senior lecturer 
Keywords: operator theory; spectral theory of differential operators 
Senior lecturer 
My current research is in complex and harmonic analysis, several complex variables, and twodimensional random growth processes 
Professor 
The field of my research is Nonlinear Functional Analysis, in particular, applications of topological and variational methods in functional analysis to nonlinear differential equations. Solutions of certain differential equations correspond to critical points of a functional (usually  though not always  of EulerLagrange type).
