Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified
Theories that can be made all-loop finite. The requirement of
all-loop finiteness leads to a severe reduction of the free parameters
of the theory and, in turn, to a vast number of predictions. Here
SU(5) FUTs are investigated in the context of low-energy
phenomenology observables. We present a detailed scanning of...

Randall-Sundrum and Horava-Witten scenarios require understanding of bulk-brane
interactions in supergravity. Whereas globally supersymmetric models with branes can
be easily and consistently constructed, there are still unresolved problems for the
locally supersymmetric cases. I will attempt to clarify the problems and report on
the progress in their resolution.

Strongly warped regions, also known as throats, are a common feature of the type IIB string
theory landscape. If one of the throats is heated during cosmological evolution, the energy is
subsequently transferred to other throats or to massless fields in the unwarped bulk of the
Calabi-Yau orientifold. This energy transfer proceeds either by Hawking radiation from the
black hole horizon...

We discuss the stabilization of the size of the extra dimension
in the 5 dimensional supergravity models compactified on an S^1/Z_2 orbifold.
We consider models with boundary superpotentials
and analyze the potential for the radion field from the viewpoint of
the 4D effective theory.
