The main research topics include supersymmetric quantum field theories, supergravity and its scalar geometry and string theory. More specifically, the computation of the low energy effective action of string compactification and the phenomenological and conceptual implications for particle physics and cosmology is a central research. A close connection with differential geometry arises from two related avenues. Firstly, the geometrical structures of the compactification manifold are directly related to properties of models in particle physics and cosmology. Secondly, the scalar sector of supergravity coincides with moduli space of the compactification manifold and mutually interesting properties have been uncovered. More recently, anti-de Sitter backgrounds of all supergravities together with their moduli spaces have been analyzed in a unified approach and the relevance for the AdS/CFT correspondence has been discussed.
