Realizing the full potential of experimental studies of nuclear matter requires a comprehensive understanding of the dynamics of its microscopic constituents, within the theory of quantum chromodynamics (QCD). Lattice QCD calculations have made significant contributions to our understanding of the strong interaction, but little is known from ab initio calculations about the dynamical properties of quarks and gluons. A central challenge for such calculations is the need to solve ill-posed inverse problems. This workshop will bring together practitioners in the field of lattice QCD and other communities working with inverse problems to address recent progress and remaining challenges in the extraction of dynamical properties from both numerical calculations and from experiment.
