Abstract: The in-medium similarity renormalization group (IM-SRG) is a recent many-body framework capable of treating medium mass nuclei using only few-nucleon forces. Recent technical developments, like the derivation of shell model interactions, have extended its reach to essentially all medium-mass nuclei. When combined with new, accurate, chiral forces rooted in underlying QCD, the IM-SRG provides a consistent framework for producing a predictive description of both energies and observables. In this talk I will review the IM-SRG framework, and then show selected results spanning isotopic chains from oxygen to tin, and compare those with results from other methods where available. I will then discuss preliminary results from other observables like transition operators. Finally, I will present the outlook for future IMSRG calculations, and how they can be improved upon.
