Tudor Ratiu at Oberwolfach in 2013

Tudor Stefan Ratiu (born March 18, 1950 in Timișoara[1]) is a Romanian-American mathematician who has made contributions to analytic geometry and dynamical systems theory.

Education

His father, Mircea Ratiu, an engineer, was the younger brother on Ion Rațiu, a well-known Romanian politician, while his mother, Rodica Bucur, was a piano professor at the Conservatory of Music in Timișoara.[2][3] Ratiu did his undergraduate studies at the University of Timișoara, completing his B.Sc. in 1973 and his M.S. in 1974.[1][4]

After moving to the United States, he completed his Ph.D. degree at the University of California, Berkeley in 1980; his dissertation, written under the supervision of Jerrold E. Marsden, was titled Euler-Poisson Equations on Lie Algebras.[5]

Career

From 1980 to 1983 he was a T. H. Hildebrandt Research Assistant Professor at the University of Michigan, after which he became an Associate Professor of Mathematics at the University of Arizona. In 1987 he moved to the University of California, Santa Cruz, where he became a Professor of Mathematics in 1988.[6].

In 1998 Ratiu moved to the École Polytechnique Fédérale de Lausanne, where he was a professor until 2015.[4] In 2014–15, he was a Professor of Mathematics at the Skolkovo Institute of Science and Technology in Russia. Since 2016 he is a professor at Shanghai Jiao Tong University in China.[4][7]

Ratiu received a Sloan Research Fellowship in 1980,[4] and he became a fellow of the American Mathematical Society in 2012.[8]
