WELCOME TO MY HOMEPAGE

HALLO, HOLA, HEI, HI! I'M A POSTDOC IN DIRK KREIMER'S GROUP AT HUMBOLDT-UNIVERSITÄT ZU BERLIN.
MY FIELD OF RESEARCH IS MATHEMATICAL PHYSICS.

I WORK ON MATHEMATICAL PROBLEMS COMING FROM PERTURBATIVE QUANTUM FIELD THEORY, IN PARTICULAR
RENORMALIZATION , THE ANALYTIC STRUCTURE OF FEYNMAN INTEGRALS AND THE ROLE OF MODULI SPACES
AND GRAPH COMPLEXES IN THIS SETTING.

RESEARCH INTERESTS

MATHEMATICAL PHYSICS. COMBINATORICS, GEOMETRY AND TOPOLOGY, ESPECIALLY THE INTERPLAY BETWEEN THESE DISCIPLINES AND THEIR APPLICATIONS IN PHYSICS. DISCRETE MATHEMATICS. SINGULARITY AND CHAOS THEORY.
