Member of project C29  of the DFG Research Center MATHEON : Numerical methods for large-scale parameter-dependent systems
on DFG-Project Numerical algorithms for generalized eigenvalue
problems of even structure with applications in robust control of
descriptor systems  at the Chemnitz University of Technology.
Diploma thesis on the topic "Analysis of higher order descriptor systems" at the TU Berlin. A summary of the most important results is available as a preprint  and has been published under the title "Contollability and observability of second order descriptor systems"  together with Prof.Dr.Volker Mehrmann.
