Job Description

We have an opening for a Postdoctoral Researcher to join our team and contribute to theory and simulation research in the exciting field of the Magnetic Fusion Energy Science. As a Postdoctoral Researcher, you will play a vital role in developing groundbreaking modelling techniques and utilizing them to tackle key challenges in boundary physics of tokamak plasmas. This research position is part of the esteemed LLNL Fusion Energy Sciences Program, situated within the Physics Division. 

You will 

  • Contribute to the advancement of numerical simulations for boundary plasmas, encompassing MHD stability, turbulence transport and divertor detachments within various operating scenarios of tokamak plasmas. Your primary objective will involve studying the operating regimes characterized by the absence of Edge-Localized Modes (ELMs) or the presence of small ELMs, while closely investigating the resulting power and particle fluxes directed towards plasma facing components.
  • Design and implement cutting-edge simulation techniques with the aim of advancing and expanding the capabilities of current tokamak codes, specifically in the realm of multiscale edge-physics modeling. Your role will involve designing methodologies and integrating them into existing codes to enable more comprehensive and accurate simulations of the intricate physics occurring at the boundary of tokamak plasmas across multiple scales.
  • Pursue independent (but complementary) research interests while collaborating with diverse experts, including plasma theorists, applied mathematicians, computer scientists and fusion experimentalists, to accomplish research objectives in a multidisciplinary team environment.
  • Contribute to research conception, design, and execution to address defined problems.
  • Publish research finding in peer-reviewed scientific or technical journals and deliver presentations of results at external conferences, seminars, and technical meetings.
  • Perform other duties as assigned.


  • PhD in Physics or a closely related discipline.
  • Experience in the development of fluid, Gyro-Landau Fluid, and/or kinetic plasma modeling codes.
  • Expertise in applying such codes, along with advanced plasma theory, to magnetic fusion plasmas, establishing connection with experiments
  • Ability to develop independent research projects, as demonstrated by a track record of publishing peer-reviewed literature.
  • Proficient verbal and written communication skills, effectively enabling collaboration in team environments and the ability to present and articulate technical information clearly.
  • Initiative and excellent interpersonal skills, and the ability to work harmoniously in a collaborative, multidisciplinary team environment.

Qualifications We Desire

  • Proficiency in programming languages, such as C++, MPI, Python, OpenMP, CUDA, RAJA, Kokkos, SYCL, and/or other scripting languages.
  • Deep knowledge on plasma edge physics, turbulence and transport theory, Gyro-Landau-Fluid models, large scale MHD simulations, as well as moment-based neutral and impurity models. 
  • Familiarity with advanced numerical methods for discretization, efficient code-coupling techniques for multi-physics, and/or preconditioners for implicit methods.
  • Expertise in machine learning techniques and demonstrate the ability to implement them effectively for large-scale and multi-physics plasma simulations

Additional Information

All your information will be kept confidential according to EEO guidelines.

Position Information

This is a Postdoctoral appointment with the possibility of extension to a maximum of three years, open to those who have been awarded a PhD at time of hire date.
