Deputy Group Leader for Nuclear, Particle, and Astrophysics Group (T-2)

What You Will Do

The Nuclear and Particle Physics, Astrophysics and Cosmology (NPAC) (T-2) Group in Theoretical Division is seeking candidates for the Deputy Group Leader (DGL) position. The successful candidate will partner with the T-2 Group Leader (GL) in providing technical leadership and management to the group. The DGL will be a member of the Theoretical Division's leadership team and will report to the T-2 GL. This is a 50% management and 50% research position, and for the research portion, the successful candidate will conduct funded research aligned with the capabilities and direction of the group.

The DGL will assist and complement the GL in ensuring effective program execution and sound fiscal management across the group's portfolio. The DGL will also perform administrative tasks in support of the group and contribute to the Theoretical Division leadership team.

T-2 conducts basic and applied theoretical research in nuclear physics, heliophysics and space domain, astrophysics, and particle theory. We have efforts in nuclear structure, the dynamics of the quark-gluon plasma, the internal structure of hadrons and the physics of high-energy scattering, the equation of state for neutron stars, lattice quantum chromodynamics, dark matter searches, and searches for new physics beyond the Standard Model using low-energy nuclear experiments, inertial confinement fusion, nuclear data evaluation, nuclear reaction theory, space physics, and the plasma physics and planet formation. Further, we actively investigate the use of machine learning and quantum computing to accelerate these efforts. T-2 has a total budget of approximately $27M and includes roughly 20 Ph.D.-level staff scientists and about 15 postdoctoral researchers and students.

T-2 collaborates with experimental groups at LANL from the Physics Division and Materials Physics and Applications Division and maintains collaborations in XCP and XTD Divisions. The group keeps very strong ties with national and international efforts in experimental NPAC science. In basic science, these include medium-energy and heavy-ion research, neutrino physics (including accelerator experiments and neutrinoless double beta decay), and fundamental neutron physics pursued at LANL and Oak Ridge National Laboratory. In applied nuclear science, they include fission and other experiments at the Los Alamos Neutron Science Center and experiments at the National Ignition Facility.

T-2's research portfolio is supported by the DOE Office of Science programs in Nuclear Physics, High Energy Physics, Fusion Energy Sciences, and Advanced Scientific Computing Research, as well as by NASA, NNSA Advanced Simulation and Computing, Physics and Engineering Models, the Laboratory Directed Research and Development program, and the Department of War.
