Statement of Interest:


My research focuses on four-dimensional string and M-theory compactifications with emphasis on both their phenomenological and mathematical aspects. This includes the study of generalized compactifications with D-branes leading to supergravity theories with a minimal amount of supersymmetry. Within these scenarios I investigate specific mechanisms to break supersymmetry and analyze the generation of soft supersymmetry breaking terms. My work also includes a detailed analysis of the $N=1$ effective action arising in type II orientifold compactifications on generic Calabi-Yau manifolds as well as a recently introduced class of generalized complex manifolds. These compactifications provide a rich supply of consistent string scenarios and I apply these general results to construct models for particle physics and cosmology. To derive important quantum corrections to these scenarios as well as to black hole vacua I also study topological string theory on the six-dimensional compact space. A detailed understanding of the classical and quantum geometry of special compactification manifolds is crucial for topological strings and essential to construct phenomenologically attractive four-dimensional compactifications.
