Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University. BSA salutes our veterans and active military members with careers that leverage the skills and unique experience they gained while serving our country. Our organization fully supports service members transitioning from active duty to civilian life and pledge’s our commitment to actively hire veterans of the U.S. Armed Forces. Military personnel who have been formally trained or have relevant experience obtained while in service may meet educational requirements and are encouraged to apply for job opportunities at BSA.

Organizational Overview

The High Energy Theory (HET) Group has active programs in all areas of Particle Physics, including Standard Model and beyond and lattice gauge techniques. We seek applicants with a strong record of research accomplishments in Particle Physics Phenomenology.

Position Description

The HET Group will have a Postdoctoral Research Associate position available beginning on or about June 1, 2023. This position will support the USQCD Lattice Gauge Theory SciDAC-5 project “Multiscale Acceleration: Powering Future Discoveries in High Energy Physics.” In this role you will assist BNL researchers and external institutions with the development of new multigrid solvers for domain wall fermions, in a project spanning theoretical physics, mathematics and computing science. Additional assistance will also contribute to developing new domain decomposed hybrid Monte Carlo sampling algorithms suited for future exascale computers. This position has a high level of interaction with an international and multicultural scientific community.

Essential Duties and Responsibilities:
