WELCOME TO MY HOMEPAGE

HALLO, HOLA, HEI, HI! I'M A POSTDOCTORAL RESEARCHER 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. TROPICAL GEOMETRY AND DISCRETE MATHEMATICS.
SINGULARITY AND CHAOS THEORY.
