Professional career
Keyfitz did her undergraduate studies at the University of Toronto,[1] and earned a Ph.D. in 1970 from New York University, under the supervision of Peter Lax.[2] Before taking her present position at Ohio State, she taught at Columbia University, Princeton University, Arizona State University, and the University of Houston; at Houston, she was the John and Rebecca Moores Professor of Mathematics. She was also the director of the Fields Institute from 2004 to 2008.[1]
She was president of the Association for Women in Mathematics from 2005 to 2006,[3] and in 2011 she became president of the International Council for Industrial and Applied Mathematics.[4] She was Vice-President of the American Mathematical Society from 2011 - 2014. [5]
Awards and honors
Keyfitz is the 2005 winner of the Krieger–Nelson Prize of the Canadian Mathematical Society, the 2011 Noether Lecturer of the Association for Women in Mathematics,[1] the 2012 winner of the SIAM Prize for Distinguished Service to the Profession, and the 2012 AWM-SIAM Sonia Kovalevsky Lecturer.[3] She was interviewed by Patricia Clark Kenschaft in her book Change is Possible:Stories of Women and Minorities in Mathematics.
In 2012 she became a fellow of the American Mathematical Society.[6] She is also a fellow of the American Association for the Advancement of Science, the Society for Industrial and Applied Mathematics[1] and the Fields Institute[5].
In 2017, she was selected as a fellow of the Association for Women in Mathematics in the inaugural class.[7]
