Research

His main area of research is in the fields of
supergravity In theoretical physics, supergravity (supergravity theory; SUGRA for short) is a modern field theory that combines the principles of supersymmetry and general relativity; this is in contrast to non-gravitational supersymmetric theories such as ...
and
particle physics Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and ...
beyond the standard model. He is one of the originators of the first supergravity theory in 1975. In 1982 in collaboration with Richard Arnowitt and Ali Hani Chamseddine, he developed the field of Applied Supergravity and the supergravity grand unification popularly known as SUGRA or mSUGRA model for gravity mediated breaking of
supersymmetry In a supersymmetric theory the equations for force and the equations for matter are identical. In theoretical and mathematical physics, any theory with this property has the principle of supersymmetry (SUSY). Dozens of supersymmetric theories e ...

CP violation In particle physics, CP violation is a violation of CP-symmetry (or charge conjugation parity symmetry): the combination of C-symmetry ( charge symmetry) and P-symmetry (parity symmetry). CP-symmetry states that the laws of physics should be t ...

He has also made contribution to studies on stability of the proton in unified models. His early work concerns the invention of effective

-pion scattering and solution to the notorious U(1) problem. His recent work has focused SO(10) grand unification, and on the Stueckelberg extensions of the Standard Model. In 1999 he was awarded the Alexander von Humboldt Prize for "basic contributions in supersymmetry and supergravity".
