Karen Vogtmann is an American mathematician born on July 13, 1949, in Pittsburg, California. She specializes in geometric group theory and gained prominence for her research work in 1986, co-authored with Marc Koller, introducing what is now known as the Koller-Vogtmann outer space. This space is a free and analog group from the Teichmüller space of a Riemann surface and is particularly useful for studying outer self-symmetry groups of the free groups generated by n, outside of the function (Fn). She is a professor at Cornell University and the University of Warwick.
