Karen E Daniels

Karen E. Daniels is an American physicist who is a professor of physics at North Carolina State University. Her research considers the deformation and failure of materials. She is a Fellow of the American Physical Society, and serves on their Committee on the Status of Women in Physics. She is also a Fellow of the American Association for the Advancement of Science.

Early life and education Daniels completed a bachelor's degree in physics at Dartmouth College in 1994. She originally planned to study engineering. After graduating, Daniels spent three years as a physics teacher at Saint Ann's School. Daniels joined Cornell University as a graduate student, earning a PhD in 2002. At Duke University, Daniels developed a technique that can make a container of granules arrange into a solid-state crystal (freeze) or into a fluid (melt) by changing the rate at which they are shaken.

Research and career Daniels joined North Carolina State University as an assistant professor in 2005. She specializes in granular materials and their force chains, and how networks within granular materials control their bulk properties. She developed a way to monitor whether granular materials reach a thermodynamic equilibrium, using plastic granules.

In 2011, Daniels spent a year as an Alexander von Humboldt Foundation fellow at the Max Planck Institute for Dynamics and Self-Organization in Göttingen, coordinating a workshop on complex system's: "Particulate Matter: Does Dimensionality Matter." She worked with Haverford College to study the naturally arising sound waves of granular materials. When the materials experience shear stress, the vibrating grains start to stick to the interface. When the stress becomes too much, several grains slip at once, rearranging into new patterns. The stick-slip transition is accompanied by low-frequency vibrational modes. She was supported by NASA to conduct experiments in zero gravity, and took a group of undergraduates to Zero Gravity Corporation.

Daniels is on the editorial board of Physical Review Letters. She serves on the American Physical Society Topical Group on Soft Matter committee. Daniels has been involved with activities to increase the representation of women in physics since the start of her career. She is part of the North Carolina State University NSF ADVANCE award "Developing Diverse Departments".
