Karen Vogtmann (born July 13, 1949 in Pittsburg, California) is an American mathematician working primarily in the area of geometric group theory. She is known for having introduced, in a 1986 paper with Marc Culler, an object now known as the Culler–Vogtmann Outer space. The Outer space is a free group analog of the Teichmüller space of a Riemann surface and is particularly useful in the study of the group of outer automorphisms of the free group on n generators, Out(Fn). Vogtmann is a Professor of Mathematics at Cornell University and The University of Warwick.
Vogtmann was inspired to pursue mathematics by a National Science Foundation summer program for high school students at the University of California, Berkeley.
She received a B.A. from the University of California, Berkeley in 1971. Vogtmann then obtained a PhD in Mathematics, also from the University of California, Berkeley in 1977. Her PhD advisor was John Wagoner and her doctoral thesis was on algebraic K-theory.
She then held positions at University of Michigan, Brandeis University and Columbia University. Vogtmann has been a faculty member at Cornell University since 1984, and she became a Full Professor at Cornell in 1994. In September 2013, she also joined the University of Warwick. She currently maintains positions both at Cornell and Warwick.
