Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2019 Best Places to Work by Glassdoor!

We have an opening for a Postdoctoral Researcher research in theoretical physics in the area of Lattice Quantum Chromodynamics (QCD), and on Lattice for Beyond the Standard Model Physics (BSM). You will play a major role in our new research direction on two nucleon interactions both in QCD and in SU(4) composite dark matter theory (Stealth Dark Matter), as well as on lattice composite Higgs theories. Emphasis will be on code development and simulation on the large LLNL supercomputers to make this research possible. You will join our collaboration with Berkeley (CalLat) on Lattice QCD and the Lattice Strong Dynamics (LSD) collaboration on Lattice BSM. This position is in the Nuclear Data & Theory Group.
 
Essential Duties
- Pursue research in zero-temperature lattice QCD with an emphasis on two-nucleon interactions.
- Pursue research in lattice SU(4) composite dark matter theory (Stealth Dark Matter)  with an emphasis on dark nucleon-nucleon interactions. This will provide the dark matter self-interaction and two-nucleon bound states in the theory.
- Pursue research in lattice composite Higgs and, in particular, on near-conformal theories.
- In collaboration with CalLat and LSD, take the lead in developing new codes and modifying existing codes for the above projects targeting the CPU-GPU LLNL unclassified supercomputer named Lassen.
- Perform the relevant numerical simulations on LLNL supercomputers.
- Engage with the CalLat and LSD collaborations.
- Pursue independent research interests and interact with a broad spectrum of scientists internal and external to LLNL.
- Perform other duties as assigned.

Qualifications
- Recent Ph.D in physics or related field.
- Experience conducting research in Lattice Field Theory.
- Experience developing computer software for Lattice Field Theory simulations.
- Experience performing Lattice QCD and/or BSM numerical simulations.
- Experience in C and C++ computer programming languages and experience with GPU, MPI, and OpenMP programming.
- Ability to perform independent research and find innovative solutions to scientific and technical problems.
- Proficient verbal and written communication skills needed to effectively present and explain results of scientific research.
- Ability to work effectively in a collaborative and multidisciplinary team environment.
Desired Qualifications
- Expertise in lattice code development relevant to CPU-GPU supercomputers.
- Expertise in lattice calculations of zero temperature observables in QCD and/or other theories and, in particular, in two meson and/or baryon scattering.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  None required.
