What is the mathematical structure of supergravity/string theory and its relation to cosmology?
Professor Kallosh works on the general structure of supergravity and string theory and their applications to cosmology. During the last few years she was mostly working on the finiteness issue of perturbative maximal supergravity trying to understand the reason for unexpected recent computations showing a better than expected ultraviolet behavior of this theory. Can this become a basis for a consistent quantum gravity?
Kallosh also studies cosmological consequences of supergravity/string theory and their implications for the theory of black holes. Her main interests are related to the models of vacuum stabilization and early universe inflation in string theory. She develops string theory models explaining the origin of the universe and its current acceleration. With her collaborators, she is analyzing possible consequences of the expected new data from the Large Hadron Collider (LHC) and the results of future cosmological observations. These results may affect the relationship between superstring theory and supergravity, and the real world. Professor Kallosh works, in particular, on future tests of string theory by CMB data and on the relation between the gravitino mass and the amplitude of gravitational waves produced during inflation.
