Radiation Belt Theory & Modeling Researcher

Description Are you searching for compelling work in the theory and modeling of radiation and energetic particle dynamics in geospace? Are you passionate about applying cutting‑edge space plasma physics research to outstanding challenges for national security? If so, we're looking for someone like you to join our team at APL! We are seeking a senior Space Plasma Physicist to join an existing numerical simulation and modeling team to conduct basic scientific research on radiation belts of Earth and other solar system planets, as well as leveraging these tools and understanding for multiple national security applications. This research position focuses on combined test‑particle and global magnetohydrodynamic (MHD) simulations of planetary radiation belts. The work will involve a mixture of fundamental science and applications spanning civil and national security space. The candidate will work in partnership with staff in the group with expertise in kinetic, test‑particle and MHD simulations, plasma theory and data analysis. The successful candidate may be expected to publish original research in peer‑reviewed journals and team with other staff to pursue external support for continued research and development for fundamental and applied simulation research as well as projects relating to past, ongoing, and future missions. The Solar & Space Physics Group (SRP) of the Space Exploration Sector has a broad and active research program that spans data analysis, theory, and modeling of planetary magnetospheres, heliospheric science, and solar physics, as well as applications to space weather and national security. The group also has significant leadership and development programs supporting space flight instrumentation and mission formulation and operations. Current mission participation includes IMAP, Parker Solar Probe, Solar Orbiter, Europa Clipper, New Horizons, EZIE, Juno, BepiColombo, and more. In addition, the group leads NASA’s multi‑institutional, cross‑disciplinary Center for Geospace Storms (CGS). Responsibilities Conduct original fundamental and applied research involving the development and adaptation of simulation codes to study space plasma systems of interest. Prepare, interpret, and present research results to team members, program managers, and sponsors. Author papers for publication in peer‑reviewed journals, when appropriate. Prepare for, present at, and attend scientific conferences, when appropriate. Develop innovative scientific research efforts and propose to compete solicitations, when appropriate. Note: This job summary and above responsibilities are for the purpose of describing the position and its essential functions at time of hire and may change over time. Qualifications Completed a PhD in Physics or in a related field. At least 5 years of demonstrated experience in high‑end plasma simulations, including any time as a postdoc. Demonstrated track record of strong communication and interpersonal skills; and Have a record of publishing first‑author scientific papers in peer‑reviewed journals. Are able to obtain TS/SCI level security clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship. Preferred Qualifications In‑depth knowledge of plasma physics, numerical methods and computational physics with applications to astrophysical and space environments, including planetary magnetospheres and stellar winds; and Extensive experience with using the advanced computational facilities from U.S. government sponsors (e.g., NASA, DOD, DOE, and/or NSF).
