Summary: Supports independent, mentored postdoctoral research in high energy density science on problems important to LLNL.
Key Information: Applicants must secure a prospective LLNL mentor’s permission before applying; fusion energy research is excluded.
The High Energy Density Science (HEDS) Center at Lawrence Livermore National Laboratory offers a competitive postdoctoral fellowship for researchers with exceptional scientific track records and potential for significant achievements. Fellows pursue their own research agendas with guidance from a senior staff scientist, typically in a collaborative, multidisciplinary team. The program usually awards one new fellowship each year.
Supported disciplines include nuclear and plasma physics, hydrodynamics, astrophysics, lasers, warm and hot dense matter, strongly coupled Coulomb systems, high-pressure science, and laser-driven dynamic compression. Research may also address matter and materials at extreme conditions, planetary and exoplanetary interiors, and giant impacts. Proposals should explain their importance and relevance to LLNL. Fellows may adapt their research plans with their mentors’ advice.
