Karen Daniels

Bio

Professor Daniels received her PhD in 2002 from Cornell University and spent 2002-5 as a postdoctoral research associate at Duke University. She joined the faculty of North Carolina State University in 2005, and was awarded a fellowship from the Alexander von Humboldt Foundation to support a yearlong sabbatical at the Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany during 2011-12. She currently serves as the Chair of the American Physical Society Division on Soft Matter.

Area(s) of Expertise

Her main research interests center around experiments on the non-equilibrium and nonlinear dynamics of granular materials, fluids, and gels. These experiments have allowed her lab to address questions of how failure occurs, how non-trivial patterns arise, and what controls the transitions between different classes of behaviors. Several of these studies have used idealized systems to provide insight into biological and geological phenomena.
