Marc Kegel

Welcome to my webpage. I am a member of the working group of Prof. Hansjörg Geiges at the Universiy of Cologne. In September 2014 I started my Ph.D. studies under the supervision of Prof. Hansjörg Geiges and graduated in January 2017 about "Legendrian knots in surgery diagrams and the knot complement problem".

The fields of my research include low-dimensional topology, contact geometry and symplectic geometry. Mainly I am interested in contact 3-manifolds, Dehn surgery constructions, open book decompositions and Legendrian- and transverse knot theory.
