Some Important Contributions:
One of the earliest papers on the background field method which is used extensively for
calculations in gauge field theories, in gravity and supergravity. The structure of 2-loop divergence in pure gravity was
predicted in this paper.

Discovered that, in supergravity with open gauge algebra, the correct Feynman rules are different from the Feynman
rules in non-Abelian gauge theories. The Faddeev-Popov ghosts acquire a 4-ghost coupling and a third type of ghost,
later called the Nielson-Kallosh ghost, is required in loop diagrams.
- Kallosh, R.E., "Modified Feynman Rules in Supergravity," Nuclear Physics B141: 141 (1978).
Discovered new phenomena in the quantization of kappa-symmetric gauge theories - the infinite dimensional
reducibility related to nilpotent gauge symmetry operators, and suggested how to quantize such theories.
- Kallosh, R.E., "Quantization of Green-Schwarz Superstring," Phys. Lett. B195:
First detailed study of stringy supersymmetric BPS black holes, with various fractions of
supersymmetry unbroken. Arguments were presented that the Bekenstein-Hawking entropy of such black holes i
protected by a supersymmetric non-renormalization theorem.

Using the Bekenstein-Hawkingrelation for the
entropy of a black hole,
gave a universal formula for the entropy of N=2 extremal black holes.
