Research Interests

My research interest lies in a variety of problems of elementary particle physics ranging from the study of basic interactions to experimental tests of fundamental theories. My background is in basic theory (effective Lagrangian of superstring and M-theory, supergravity, and general relativity) as well as in phenomenology (implications of extended gauge structures and phenomenological implications of string theories), and I tend to pursue research that bridges the gap between basic theory and the experimental consequences of these theories. My main research contributions have been along the following directions:

Constructions of four-dimensional solutions of superstring theory and derivations of their phenomenological implications. Within heterotic string theory, my study of couplings of (blown-up) orbifold compactifications in mid/late eighties are noted. The program on physical implications of classes of semi-realistic heterotic string models in the mid/late nineties was one of the very few strong efforts, pursuing the "top-down" approach connecting developments in formal theory with possible phenomenological implications. Recent efforts have focused on open string constructions resulting in first examples of supersymmetric solutions three-family standard-like and grand unified models, as well as first constructions of semi-realistic models with stabilized moduli. These models have an interpretation as M-theory compactified on seven-dimensional manifolds with G2 holonomy, thus probing a new corner of M-theory, that is generating considerable activity in both the physics and mathematics communities.

Nonperturbative gravitational physics in fundamental theory. This effort was initiated in the early nineties and led to pioneering work on domain walls and black holes in supergravity and superstring theory. It resulted in the first examples of supersymmetric walls and a subsequent unifying description of such configurations. These solutions have subsequently found a realization within five-dimensional supergravity as gravity trapping solutions. The recent effort focused on the study of such configurations both from the point of view of phenomenological implications as well as from AdS/CFT correspondence.

In mid/late nineties a broad program on black holes in string theory resulted in the first examples of

supersymmetric black holes in string theory, suitable for the study of black hole microscopics. Subsequent efforts have shed light on properties of general rotating black holes that contributed to dramatic progress in the study of their microscopic properties. Most recent effort involves constructions of general charged spinning black holes in asymptotically anti-de Sitter spaces.

In the past few years these efforts have grown in scope and impact and have focused on a comprehensive study of consistent non-linear Kaluza-Klein compactifications of string and M-theory and studies of M-theory dynamics on spaces with special holonomy, such as Spin(7) and G2, making forefront contributions at the interface of differential geometry and formal M-theory.
