Sherrell Greene

Owner and Founder, Advanced Technology Insights


Supervising Faculty: Howard Hall

During a career spanning over three decades at Oak Ridge National Laboratory (ORNL), Sherrell Greene rose from individual contributor to the position of Director of Research Reactor Development Programs and Director of Nuclear Technology Programs.  Under Sherrell’s leadership, ORNL’s Nuclear Technology Programs portfolio grew in just seven years from less than $20M/yr. to ~ $125M/yr. in research, development, and demonstration activities sponsored by eleven offices in four federal agencies – as well as a multitude of international collaborations and commercial partnerships.  He has extensive experience working with senior leadership in the U.S. Department of Energy (DOE), the National Nuclear Security Administration (NNSA), the Nuclear Regulatory Commission (NRC), and the National Aeronautics and Space Administration (NASA) – as well as a host of private sector companies both nationally and internationally. 

A nuclear engineer by training (Sherrell is an internationally recognized expert in commercial nuclear power severe accident safety), and a student of human nature by heart, Sherrell has worked with a variety of scientific and technical organizations throughout North America, Russia, Europe, and Asia.  His views and perspectives on complex technical issues have been sought by a variety of public media outlets, including National Public Radio, The Economist, Popular Science, Wired Magazine, and Japan’s NHK television network.

Sherrell founded Advanced Technology Insights, LLC in January 2012, where he serves as a technical and leadership consultant, and critical communications trainer, to organizations and individuals seeking to maximize their success in challenging scientific and technical business environments.  He returned to UTK in the Fall of 2016 as a full-time PhD student.


Sherrell’s PhD research is focused on the role of electricity and energy in modern society, bulk electric power system (“Grid”) resiliency, and the potential role existing and future nuclear power plants could play in enhancing the security and resiliency of the U.S. Grid – particularly with respect to Black Sky Events (massive and prolonged failures of the Grid due both to natural and human-initiated events).
