Quantum criticality is a popular aspect of modern quantum many-body physics. In this talk, I will give an overview of its applications to Mott insulating solid state materials. In particular I will discuss advances in our theoretical understanding of unusual quantum critical phenomena, as well as recent progress in identifying quantum criticality both in experiments on complex materials (using the example of Ising criticality in CoNb2O6) and numerical simulations of model quantum Hamiltonians of SU(N) symmetric anti-ferromagnetic Mott insulators
