Alex Eskin

Alex Eskin (Russian: Александр Григорьевич Эскин, born May 19, 1965, Moscow, USSR^[1]) is an American mathematician. He is the Arthur Holly Compton Distinguished Service Professor in the Department of Mathematics at the University of Chicago.^[2] His research focuses on rational billiards and geometric group theory.

Biography

Eskin was born in Moscow on May 19, 1965.^[1][2][3] He is the son of a Russian-Jewish mathematician Gregory I. Eskin (b. 1936, Kiev), a professor at the University of California, Los Angeles. The family emigrated to Israel in 1974 and in 1982 to the United States.^{[citation needed]}

Eskin earned his doctorate from Princeton University in 1993, under the supervision of Peter Sarnak.^[4]

Eskin has been a professor at the University of Chicago since 1999.^[5]

Awards

Eskin gave invited talks at the International Congress of Mathematicians in Berlin in 1998,^[6] and in Hyderabad in 2010.^[7]

For his contribution to joint work with David Fisher and Kevin Whyte establishing the quasi-isometric rigidity of solvable groups, Eskin was awarded the 2007 Clay Research Award.^[8] In 2012, he became a fellow of the American Mathematical Society.^[9] In April 2015, Eskin was elected a member of the United States National Academy of Sciences.^[5][10] Eskin won the 2020 Breakthrough Prize^[11][12] in mathematics for his classification of ${\displaystyle P}$-invariant and stationary measures for the moduli of translation surfaces,^[13] in joint work with Maryam Mirzakhani.
