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.
