A theoretical physicist whose teaching develops the renormalization group as a way to understand critical phenomena. His position-space treatment replaces microscopic variables with coarser variables and follows the changing interactions. Repeating this operation exposes renormalization-group fixed points, explaining how systems with different microscopic details can share large-scale behavior.[ref]
