Abstract: Lattice field theory provides a non-perturbative regularization suitable for strongly interacting systems, which has proven crucial to the study of quantum chromodynamics among many other theories. Lattice investigations of supersymmetric field theories have a long history but often struggle due to the interplay of supersymmetry with the lattice discretization of space-time. I will discuss a way around these difficulties for maximally supersymmetric Yang--Mills theories, which are a cornerstone of holographic duality. After reviewing some highlights of the lattice formulation, I will present a selection of results from recent and ongoing numerical studies, including tests of holography.
