Statement of Interest:


  My current interest is in flux compactifications in string theory.
The generic supersymmetric flux geometries are non-Kahler.
Mathematically, non-Kahler geometries represent an exciting area in
mathematics that has not been much studied.  Physically, it is
important to work out the relation between the observables of the
four-dimensional effective theory and the parameters of non-Kahler
background solutions.
 
 Moreover, many interesting aspects of Calabi-Yau compactifications
can be reconsidered in the non-Kahler setting.  Issues like
supersymmetric cycles, mirror symmetry, and geometric transitions may
have very interesting generalizations in non-Kahler supersymmetric
backgrounds.  Such analyses will most likely require new mathematical
tools (for example, Hitchin's generalized complex geometry) and lead
to the discovery of new physical phenomena in the yet uncharted
regions of the string theory landscape.
