Since November 2018 working for Google, Switzerland in Zürich.

Previous temporary professorships in Mathematics, Researcher/Privatdozent in Mathematics (chronologically decreasing order):

  • Free University of Berlin (Germany)
  • Institute of Mathematics of the Czech Academy of Sciences (Czech Republic)
  • University of Rostock (Germany)
  • University of Gießen (Germany)
  • Univesrity of Eichstätt (Germany)
  • University of Würzburg (Germany)

Research interest mainly: Linear and Nonlinear Analysis, including but not restricted to:

  • toppological and geometric methods (e.g. degree and Nielsen theory, Morse index, multivalued maps)
  • partial and ordinary differential equations, particularly reaction-diffusion systems nonsmooth problems (obstacle problems, variational inequalities, differential inclusions, …)
  • linear and nonlinear spectral theory
  • particular operators (Urysohn, Hammerstein, superposition operators)
  • nonlinear dynamical systems and bifurcation theory
  • integral equations (also of vector functions)
  • Volterra and functional differential equations
  • function spaces; in particular, spaces of measurable functions
  • positive operators and lattices
  • Weyl calculus and noncommutative harmonic analysis
  • connections with logic and set theory (axiom of choice, continuum hypothesis)
  • nonstandard analysis
  • measure and integration theory (also finitely additive measures)
  • geometry of normed spaces
