Anita Layton is the Robert R. and Katherine B. Penn Associate Professor of Mathematics at Duke University. She is the author, along with Aurelie Edwards, of the Lecture Notes on Mathematical Modeling in the Life Sciences volume Mathematical Modeling of Renal Physiology (2013). Her research focuses on mathematical physiology, multiscale numerical methods, and numerical methods for immersed boundary problems. Laura Miller is Associate Professor of Biology and Mathematics at the University of North Carolina at Chapel Hill, where she also serves as Principal Investigator of the Mathematical Physiology Group. Her research examines the developmental and evolutionary significance of fluid dynamic forces in biological systems, particularly how biological structures have evolved to increase fluid transport and locomotion efficiency, the way fluid forces constrain biological design, and the influence of fluid scaling effects during animal development.
