  We propose a dynamical mean field approach for calculating the electronic
structure of strongly correlated materials from first principles. The scheme
combines the GW method with dynamical mean field theory, which enables one to
treat strong interaction effects. It avoids the conceptual problems inherent to
conventional ``LDA+DMFT'', such as Hubbard interaction parameters and double
counting terms. We apply a simplified version of the approach to the electronic
structure of nickel and find encouraging results.
