Justin L Whitt


Justin Whitt is currently the project manager for the LEGEND-1000 project within the Nuclear Physics Division where he draws on over 30 years of experience to design and implement the management controls, procedures, and systems for successful deployment of the LEGEND-1000 experiment.

He previously served as the program director for the Department of Energy’s Oak Ridge Leadership Computing Facility (OLCF) and was responsible for acquiring and operating the leadership class computer systems and infrastructure to enable scientific discoveries at every scale—including breakthroughs that would not otherwise be possible. He led the project to deliver the world's first exascale supercomputer called Frontier, which is capable of over a quintillion calculations each second.

Justin joined the staff at Oak Ridge National Laboratory (ORNL) in 2009 as a computational scientist with the Joint Institute for Computational Sciences (JICS), where he worked with scientists to develop applications capable of using the Kraken supercomputer (the first academic petascale computer). He later held several leadership positions at JICS and served on the leadership team for the National Science Foundation’s eXtreme Science and Engineering Discovery Environment (XSEDE).

Prior to joining ORNL, Justin worked as a researcher at the University of Tennessee’s National Center for Computational Engineering where he used computer modeling and simulation to study the aerodynamics of aircraft and wind turbines.
