Postdoctoral Fellow

Position Overview

A postdoctoral position is available in the Department of Physics at the University of Idaho. The primary focus of this position is advancing numerical relativity methods for compact binary systems. The scholar will conduct research by extending the Einstein Toolkit, Black Holes@Home, and the super

B project to perform state‑of‑the‑art simulations of compact binaries (including binary black holes, binary neutron stars, and black hole–neutron star binaries). The broader goals are to generate accurate predictions for gravitational‑wave and multimessenger signals and to explore challenging regimes of parameter space.

• Demonstrated research in numerical relativity, computational general relativity, or a closely related area of computational physics.
• Experience with PDE solvers (elliptic and/or hyperbolic), numerical methods, and scientific software development.
• Proficiency in C/C++ and Python, with experience in HPC environments (e.g., MPI/OpenMP; GPU experience a plus).
• Record of peer‑reviewed publications appropriate to career stage.

• Ph.D. in Physics, Astrophysics, Applied Mathematics, Computer Science/Engineering, or a closely related field by the start date.

• Strong scientific communication skills (written and oral).
• Ability to work independently and collaboratively within a team.
• Commitment to reproducible research (version control, testing, documentation).
• Experience generating binary black hole initial data on curvilinear/multipatch/multidomain/AMR grids.
• Experience with Einstein Toolkit, NRPy / NRPyElliptic, GRHayL, Illinois
  
  GRMHD, or comparable /GRMHD codes.
• Background implementing or benchmarking radiation transport (neutrino or photon) in GR.
• Workflow on supercomputers (e.g., Slurm/PBS), CI/testing, and contributions to open‑source scientific software.
• Familiarity with gravitational‑wave modeling and catalog/campaign paper authorship.

• None
