Timeline

1949

Karen Vogtmann (born July 13, 1949 in Pittsburg, California ) is an American mathematician working primarily in the area of geometric group theory.

1971

She received a B.A. from the University of California, Berkeley in 1971.

1977

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.

1984

Vogtmann has been a faculty member at Cornell University since 1984, and she became a full professor at Cornell in 1994.

1986

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.

Since 1986 Vogtmann has been a co-organizer of the annual conference called the Cornell Topology Festival that usually takes places at Cornell University each May.

Vogtmann's most important contribution came in a 1986 paper with Marc Culler called "Moduli of graphs and automorphisms of free groups".

The paper introduced an object that came to be known as Culler–Vogtmann Outer space.

The Outer space Xn, associated to a free group Fn, is a free group analog of the Teichmüller space of a Riemann surface.

Instead of marked conformal structures (or, in an equivalent model, hyperbolic structures) on a surface, points of the Outer space are represented by volume-one marked metric graphs.

A marked metric graph consists of a homotopy equivalence between a wedge of n circles and a finite connected graph Γ without degree-one and degree-two vertices, where Γ is equipped with a volume-one metric structure, that is, assignment of positive real lengths to edges of Γ so that the sum of the lengths of all edges is equal to one.

2003

Vogtmann has been the vice-president of the American Mathematical Society (2003–2006).

2006

Vogtmann is a former editorial board member (2006–2016) of the journal Algebraic and Geometric Topology and a former associate editor of Bulletin of the American Mathematical Society.

She is currently an associate editor of the Journal of the American Mathematical Society, an editorial board member Geometry & Topology Monographs book series, and a consulting editor for the Proceedings of the Edinburgh Mathematical Society.

She is also a member of the ArXiv advisory board.

Vogtmann gave an invited lecture at the International Congress of Mathematicians in Madrid, Spain, in August 2006.

2007

She gave the 2007 annual AWM Noether Lecture titled "Automorphisms of Free Groups, Outer Space and Beyond" at the annual meeting of American Mathematical Society in New Orleans in January 2007.

Vogtmann was selected to deliver the Noether Lecture for "her fundamental contributions to geometric group theory; in particular, to the study of the automorphism group of a free group".

2008

She has been elected to serve as a member of the board of trustees of the American Mathematical Society for the period February 2008 – January 2018.

2010

On June 21–25, 2010 a 'VOGTMANNFEST' Geometric Group Theory conference in honor of Vogtmann's birthday was held in Luminy, France.

2012

In 2012 she became a fellow of the American Mathematical Society.

2013

In September 2013, she also joined the University of Warwick.

She is married to the mathematician John Smillie.

The couple moved in 2013 to England and settled in Kenilworth.

She is currently a professor of mathematics at Warwick, and a Goldwin Smith Professor of Mathematics Emeritus at Cornell.

2014

Vogtmann received the Royal Society Wolfson Research Merit Award in 2014.

She also received the Humboldt Research Award from the Humboldt Foundation in 2014.

2016

She was named MSRI Clay Senior Scholar in 2016 and Simons Professor for 2016-2017.

Vogtmann gave a plenary talk at the 2016 European Congress of Mathematics in Berlin.

2018

In 2018 she won the Pólya Prize of the London Mathematical Society "for her profound and pioneering work in geometric group theory, particularly the study of automorphism groups of free groups".

In May 2021 she was elected a Fellow of the Royal Society.

In 2022 she was elected to the National Academy of Sciences (NAS).

Vogtmann's early work concerned homological properties of orthogonal groups associated to quadratic forms over various fields.

2020

She became a member of the Academia Europaea in 2020.

She was elected to the American Academy of Arts and Sciences in 2023.
