Nuclear Astrophysics Postdoctoral Researcher - LANL

External Positions

What You Will Do

The Nuclear Astrophysics team at Los Alamos National Laboratory (LANL) invites applications for one or more open postdoctoral positions to begin in 2024. Candidates will work closely with T-2 (Nuclear and Particle Physics, Astrophysics and Cosmology) and ISR-1 (Space Science and Applications) researchers. Selected applicants are expected to have a Ph.D. in mathematics, physics, scientific computing, or a closely related field by the beginning of the postdoctoral appointment.

Our groups conduct research on a broad set of topics. In theoretical nuclear astrophysics we study nuclear structure, reaction mechanisms, and fission properties relevant for the study of nucleosynthesis. Focus areas in space-based applications include the development of modeling techniques to understand radioisotope buildup on orbiting spacecraft, and their impacts on ongoing scientific gamma-ray astrophysics missions.

LANL scientists working in these areas include Kurtis Bartlett, Chris Fryer, Oleg Korobkin, Jonah Miller, Wendell Misch, Matthew Mumpower, Tony Shin, and Karl Smith. We collaborate actively with our colleagues throughout the laboratory and have close ties with ongoing efforts in experimental sciences.

The open positions provide an excellent opportunity for an early career scientist to develop an independent research program in the exciting field of nuclear astrophysics. Candidates with expertise in any of the aforementioned areas are strongly encouraged to apply. Exceptionally well qualified candidates may be considered for a Director's Postdoctoral Fellowship or Distinguished Postdoctoral Fellowship.

Postdoctoral positions at LANL are for two years with a possible third year contingent on funding and performance. Interested applicants should submit their application (CV, research statement, and three letters of recommendation) by Jan. 1, 2024, for full consideration.

The successful candidate will:

  • Gain experience in theoretical and computational modeling of nuclear astrophysics phenomena.
  • Publish research in leading scientific journals.
  • Develop strong programming skills.
  • Work both independently and in a team environment to solve problems in support of Laboratory missions.
