Research interests

My main research focus lies in the study of dualities of string and M-theory and their geometrical description via generalised (exceptional) geometry - in particular its appearance in the world-volume descriptions of string and M-theory and its use in the study Poisson-Lie T-duality.
Connected to generalised geometry are my interests in the study of integrability, in particular the study of the classical integrability of string sigma models in certain backgrounds. Methods of generalised geometry helped to generate and understand new integrable sigma models.
