Aimee Sue Anastasia Johnson is an American mathematician who works in dynamical systems.
She is a professor of mathematics at Swarthmore College,[1] the winner of the George Pólya Award, and the co-author of the book Discovering Discrete Dynamical Systems.
[2] She completed her Ph.D. in 1990 at the University of Maryland, College Park; her dissertation, Measures on the Circle Invariant for a Nonlacunary Subsemigroup of the Integers, was supervised by Daniel Rudolph.
[3] In dynamical systems, Johnson is known for her work on a conjecture of Hillel Furstenberg on the classification of invariant measures for the action of two independent modular multiplication operations on an interval.
[2] In 2017, Madden, Johnson, and their co-author Ayşe Şahin published the textbook Discovering Discrete Dynamical Systems through the Mathematical Association of America.
