## Symbolic dynamics for geodesic flows## Phoenix, Arizona, 2004
After emigrating to the United States in 1978, she returned to research mathematics and entered the Ph.D. program at the University of Maryland. She changed her research area from dynamical systems to number theory and completed her degree under Don Zagier in 1983. She was awarded an NSF postdoc and was associated with Caltech and four campuses of the University of California before moving to Penn State in 1990, where she was promoted to full professor in 1993. Her mathematical interests center on the interaction between number theory, geometry and dynamical systems with the latter field, her first mathematical specialty, coming to the fore in the last decade. She has a life-long interest in mathematical education, which has borne such diverse fruits as innovative programs for primary school students from the Soviet period, the popular graduate text Fuchsian Groups and the unique MASS program for undergraduates at Penn State that she created together with her husband Anatole Katok. The topics of her many invited talks are quite varied, ranging from her mathematical research to models for integrating research into the undergraduate experience. In 1995 she founded She has three children whose careers range from operations research to software development and architecture to classical singing. |
