The positive resolution of the geometrization conjecture shows that geometric structures (i.e., complete locally homogeneous metrics) play a special role in our understanding of the taxonomy of three-dimensional manifolds. In light of this, we initiate the exploration of the extent to which three-dimensional geometric structures are determined by their spectra. For example, we find that among locally homogeneous manifolds, closed three-manifolds modeled on six of the eight Thurston geometries are determined up to universal Riemannian cover by their spectra, a result that includes all compact locally symmetric spaces. More generally, we obtain results concerning spaces modeled on ``metrically maximal geometries.''

Joint work with Samuel Lin (Dartmouth College, USA) and Benjamin Schmidt (Michigan State University, USA).
