Willy Fischler

Willy Fischler is a theoretical physicist. He is the Jane and Roland Blumberg Centennial Professor of Physics at the University of Texas at Austin, where he is affiliated with the Weinberg theory group. He is also a certified Flight Paramedic and was a Licensed Paramedic with Marble Falls Area EMS and a volunteer EMT with the Westlake Fire Department.
His contributions to physics include:

Early computation of the force between heavy quarks.
The DFSZ model, 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.
