Biography
Nancy Lybeck is the Department Manager for the Instrumentation, Controls, and Data Science Department at Idaho National Laboratory. Dr. Lybeck has extensive experience in data processing and analysis using the SAS programming environment and MATLAB, and served as the technical lead for the Nuclear Data Management and Analysis System from 2014 to 2017. From 2011 to 2015, Nancy served as co-principal investigator of a Light Water Reactor Sustainability project to demonstrate the application of diagnostics and prognostics in the current fleet of nuclear power plants. She has also provided modeling and analysis in support of code qualification of Alloy 617 for use in nuclear applications, statistical support for the HPRR fuel qualification program, and general analytical support for a variety of projects at INL. Nancy graduated from Montana State University with a Ph.D. in Mathematics (with an emphasis in numerical analysis), followed by a postdoctoral fellowship in industrial mathematics at the Center for Research in Scientific Computation at North Carolina State University. Prior to joining the INL in January 2010, she worked for Sentient Corporation, where she served as a principal investigator for several small business innovation research projects in the area of prognostic health management.
