Stephen L. Adler
In a series of remarkable, difficult calculations, Stephen Adler demonstrated that abstract ideas about the symmetries of fundamental interactions could be made to yield concrete predictions. The successful verification of these predictions was a vital step toward the modern Standard Model of particle physics. In some of his more recent work, he has been exploring generalized forms of quantum mechanics, both from a theoretical and a phenomenological standpoint, and implications for gravitational physics. He has developed new algorithms for multidimensional integration, and is currently exploring a particle unification model based on boson-fermion balance without full supersymmetry.
