**Quantum Monte Carlo applications to atomic nuclei and neutron matter**

Understanding how the structure and dynamics of nuclei and infinite nuclear matter emerge from the individual interactions between neutrons and protons is a long-standing goal of nuclear theory. The non-perturbative nature and strong spin-isospin dependence of nuclear interactions make solving the many-body Schrödinger equation a highly non-trivial task. Quantum Monte Carlo methods use stochastic techniques to overcome these difficulties and accurately model short- and long-range nuclear dynamics. In this talk, I will present our recent calculations of the electroweak responses and matrix elements relevant to neutrino-less double-beta decay searches. I will then discuss the equation of state of infinite neutron matter, as obtained from local, chiral interactions that explicitly account for the excitation of the Delta resonance. Finally, I will provide some prospects on using artificial neural networks to compactly represent the wave functions of atomic nuclei and translational-invariant systems.
