Full Story
David Fisher is the Ruth N. Halls Professor of Mathematics in the College of Arts and Sciences at IU Bloomington. His research as a pure mathematician has made critical contributions to quasi-isometric rigidity of polycyclic groups and arithmeticity of hyperbolic manifolds. His breakthrough work, in collaboration with others, solved Zimmer's conjecture, an open mathematical question since the early 1980s.
Fisher is the editor of four top math journals: Journal of Topology and Analysis, Geometriae Dedicata, Indiana University Mathematics Journal, and Geometry and Topology. He has been continuously funded by the National Science Foundation since 1999.
