• Early computation of the force between heavy quarks.
• The invisible axion, as a solution to the strong CP problem.
• The cosmological effects of the invisible axion and its role as a candidate for dark matter.
• Pioneering work on the use of supersymmetry to solve outstanding problems in the standard model of particle physics.
• The first formulation of what became known as the "moduli problem in cosmology".
• The Fischler-Susskind mechanism in string theory.
• The original formulation of the holographic entropy bound in the context of cosmology.
• The discovery of M theory, or BFSS Matrix Theory. M theory is an example of a gauge/gravity duality .
• Black Hole production in colliders.
