Young studied mathematics at the University of Wisconsin in Madison (Bachelor 1973) and the University of California, Berkeley , where she received her master’s degree in 1976 and her PhD in 1978 with Rufus Bowen (Entropy and symbolic dynamics of certain smooth processes). But her first work appeared in 1977. As a post-doc she was at Northwestern University , from 1980 at Michigan State University , where she became an associate professor in 1984, from 1987 at the University of Arizona , where she became a professor in 1990. From 1990 she was a professor at the University of California, Los Angeles (UCLA) and from 1999 at the Courant Institute of Mathematical Sciences of New York University , where she is Henry and Lucy Moses Professor of Natural Science and Professor of Mathematics. She was visiting scholar at the University of Warwick , the Mathematical Sciences Research Institute (MSRI) in Berkeley, the University of Bielefeld , the Institute for Advanced Study , the Collège de France in Paris.

Young dealt with ergodic theory , chaotic dynamic systems, strange attractors , dynamic complexity, the effect of noise in the long-term behavior of dynamic systems, probabilistic laws for the behavior of chaotic systems.

With Michael Benedicks and Quidong Wang she developed the theory of chaotic rank 1 attractors , originally a result of the work of Benedicks and Lennart Carleson on Henon attractors.

In 1985 she was a Sloan Research Fellow and in 1993 she received the Ruth Lyttle Satter Prize . In 1997 she was a Guggenheim Fellow and since 2004 she has been a Fellow of the American Academy of Arts and Sciences , and since 2020 a member of the National Academy of Sciences . She was invited speaker at the International Congress of Mathematicians (ICM) in Zurich in 1994 (Ergodic theory of attractors) . In 2005 she was a Noether Lecturer . In 2007 she gave the Sonya Kovalevsky Lectures of the Society for Industrial and Applied Mathematics (SIAM) and became a member of the Hungarian Academy of Sciences . In 2018 she is plenary speaker at the ICM in Rio (Dynamical systems evolving) .
