Abstract: How do we ensure security in internet communications, for example, when using a credit card to make an online purchase? How do we efficiently transmit or store data, such as satellite pictures from outer space or music on a CD, in such a way that we can reliably read that data even in the presence of noise, such as electronic interference or a scratch or dust? In this talk, we will see that the answers to both of these questions hinge on beautiful mathematics that was once thought to be too abstract to be of any practical use.

She has been at the University of Nebraska Lincoln since 1996, and currently serves as Aaron Douglas Professor and Chair of the Department of Mathematics there. She spent much of the fall 2011 semester as a Visiting Professor at Centre Interfacultaire Bernoulli, EPFL in Lausanne, Switzerland as part of a special program in her research area of coding theory. Among her invited lectures are the AMS-MAA Joint Invited Address at the 2013 MathFest in Hartford, CT and a plenary lecture at the 2015 SIAM Conference on Applied Algebraic Geometry in Daejeon, South Korea. Walker is a co-founder of the Nebraska Conference for Undergraduate Women in Mathematics and has served as an elected member of the AWM Executive Committee and the AMS Council. She has won several teaching awards, including the Deborah and Franklin Tepper Haimo Award from the MAA and the Outstanding Teaching and Instructional Creativity Award from the University of Nebraska system.
