ORAU
Astrophysics: Theoretical Cosmic‑Ray Astrophysics
Join the NASA Postdoctoral Program (NPP) as a postdoctoral fellow to conduct theoretical research on cosmic‑ray phenomena at the Goddard Space Flight Center in Greenbelt, Maryland.
Responsibilities
Develop Monte Carlo simulations to study particle acceleration in plasma shocks.
Construct analytic models of charged‑particle propagation through disordered magnetic fields.
Investigate shock‑acceleration theories and their role in shaping the high‑energy spectrum.
Examine cosmic‑ray composition changes resulting from interstellar collisions.
Explore the origin of light elements (Li, Be, P) and the cosmic‑ray knee at ~3×10^15 eV.
Collaborate with the Laboratory for High‑Energy Astrophysics to advance NASA’s missions in space science.
Qualifications
Doctoral degree in astrophysics, high‑energy physics, or a related field.
U.S. citizen, lawful permanent resident (LPR), foreign national eligible for a J‑1 visa, or LPR applicant in the U.S. with I‑485 or I‑589 status and a valid EAD card.
Strong background in theoretical astrophysics, plasma physics, or cosmic‑ray research.
Experience in numerical simulations, Monte Carlo methods, or analytic modeling of astrophysical systems.
Excellent written and oral communication skills.
Application Process All applications must be submitted through the NASA Postdoctoral Program website. A complete application includes:
Research proposal outlining the scientific goals and methods.
Three letters of recommendation.
Official doctoral transcript documents.
Application deadline: March 1 2026 6:00:59 PM Eastern Time Zone.
