                                       Research Interests;

                                       My recent research interest is the role of Knot -Theory in renormalizable
                                       perturbative Quantum Field Theory (rpQFT) especially the relationship of
                                       Vassiliev -Invariants, Weight-Systems and the Kontzevich -Universal-
                                       Integral -Invariant with Feynman Diagramms and Number- Theory.
                                       Another topic is the Hopfalgebra-Structure of rpQFT.
