Thom Mason. An American physicist and laboratory director known for his leadership at major United States Department of Energy research facilities. His career has spanned significant roles at Oak Ridge National Laboratory and Los Alamos National Laboratory, where he oversaw large-scale scientific and national security missions. Mason's scientific expertise lies in condensed matter physics and the use of neutron scattering to study materials.

Early life and education

Mason completed his undergraduate studies in physics at the University of Toronto, a major research institution in Canada. He then pursued his doctoral degree, earning a Ph.D. in physics from McMaster University, where his research focused on experimental techniques in condensed matter physics. His graduate work provided a foundation in the use of neutron sources, which would become central to his later scientific career. This academic training positioned him for a research role within the expansive United States Department of Energy laboratory system.

Career at Oak Ridge National Laboratory

Mason joined Oak Ridge National Laboratory in Tennessee, a leading center for neutron scattering research. He rose through leadership positions, eventually becoming the director of the Spallation Neutron Source, one of the world's most powerful accelerator-based neutron sources. In this role, he managed the facility's operations and scientific user program, supporting research across fields like materials science and chemistry. His successful tenure led to his appointment as the laboratory's director, where he oversaw a broad portfolio including nuclear energy research, computational science, and biological systems studies.

Leadership at Los Alamos National Laboratory

In 2018, Mason was appointed director of Los Alamos National Laboratory in New Mexico, managed by the Triad National Security, LLC consortium. This role placed him at the helm of a premier institution responsible for the United States nuclear weapons stockpile stewardship and a wide array of national security science. He guided the laboratory's missions in areas such as global security, space exploration, and supercomputing, including the work conducted at the Los Alamos Neutron Science Center. His leadership emphasized integrating the laboratory's defense programs with its open scientific research initiatives.
