Cohomology of graph products of infinite groups with group ring coefficients

I will explain a computation of the cohomology of any graph product of infinite groups in terms of the factor groups. For example, this gives a calculation for right-angled Artin groups, which are, by definition, graph products of copies of the infinite cyclic group. The method of proof is a simple spectral sequence argument which I don't think has been used previously.
