Einstein Fellow Group
Our research lies at the interface between mathematical and high-energy physics. We are interested in fundamental properties of gauge and string theories, and on developing general methods for the quantitative study of their quantum behavior and their relation via the AdS/CFT correspondence.
We are supported by the Einstein Foundation Berlin, the Research Training Group “Rethinking Quantum Field Theory”, the EU-funded Marie Sklodowska-Curie Innovative Training Network EuroPLEx and the Kolleg Mathematik Physik Berlin.
