Alex Eskin

Alex Eskin ( born May 19, 1965 in Moscow ) is a Russian -born American mathematician, the terrain of geometric group theory, ergodic theory and dynamical systems ( billiards ), Lie groups with applications in number theory employs.

He studied mathematics at the University of California, Los Angeles ( Bachelor 1986), followed by physics until 1989 at the Massachusetts Institute of Technology. In 1991, he continued to study mathematics at Stanford University and his doctorate in 1993 from Princeton University with Peter Sarnak ( Counting lattice points on homogeneous varieties ). 1993/94 he was a postdoctoral fellow at the Institute for Advanced Study. After that, he was at the University of Chicago, first as Dickson Instructor, from 1997 as an associate professor and from 1999 as a professor.

He worked among others with the dynamics and geometry of Teichmüller spaces, geometric group theory, ergodic theory in Lie groups and billiards in rational polygons.

1992/93 he was a Sloan Fellow and from 1997 to 2002 Packard Fellow. In 2007 he was awarded the Clay Research Award, particularly for joint work with David Fisher and Kevin Whyte, which showed the rigidity of groups quasi- isometric to the three-dimensional solvable Lie group Sol. In 2010 he was invited speaker at the International Congress of Mathematicians in Hyderabad ( quasi- isometric rigidity of solvable groups with David Fisher) and in Berlin in 1998 ( Counting problems and semisimple groups). He is a Fellow of the American Mathematical Society.
