new Kegel

Marc Kegel

Welcome to my webpage. Since August 2018 I am a BMS Substitute Professor in the working group of Prof. Chris Wendl at the Humboldt University Berlin.

From September 2014 till July 2018 I was a member of the working group of Prof. Hansjörg Geiges at the Universiy of Cologne where I 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.
