Who I am and what I do

I am a mathematician/mathematical physicist and a researcher in mathematics education at the Faculty of Mathematics at the University of Vienna.
I am a member of the research group DiANA
(Differential Algebras and Nonlinear Analysis) in the Analysis, Geometric Structures and Mathematical Physics section of the department.
My research interests include:
 mathematical physics/mathematical general relativity:
spacetime singularities, cosmic censorship, exact radiative spacetimes, impulsivge gravitational waves
 mathematics education:
professional knowledge of teachers, beliefs on teaching and learning mathematics
 (applied) mathematics:
generalized functions, theory of PDE, kinetic theory, time frequency analysis & modulation spaces

Also I am member and treasurer of the IAGF (The International Association for Generalized Functions), a lifetime member of ISAAC (The International Society for Analysis, its Applications and Computation), and a member of GDM (The German Society of Didactics of Mathematics).
My teaching includes a variety of courses in several areas of mathematics reaching from general firstyearcourses to specialized courses and seminars in analysis, PDE and geometry, as well as major courses in the teacher’s training programme
I am a supervisor both in the
I have coauthored the general introductory book Einführung in das Mathematische Arbeiten (German,Introduction into mathematical methodology) with Hermann Schichl. Together we are running a service web page accompanying the book. We have been awarded the UNIVIE Teaching Award 2013 of Vienna University and the Ars Docendi 2016, the Austrian National Award in University Teaching.
