In 1986, she became the first female program director for probability theory at the National Science Foundation, in the same year that Nancy Flournoy became its first female program director for statistics. She was named a Fellow of the Institute of Mathematical Statistics in 1988, "for outstanding and noteworthy contributions to probability theory and its applications, for work in extreme value theory, and for dedicated and conscientious service to the profession and to the IMS". In her retirement from Arizona, she has become an avid origami folder.
