Description Job Title Postdoctorial Research Associate Location Los Alamos, NM, US Organization Name T-3 / Fluid Dynamics And Solid Mechanics Minimum Salary Maximum Salary What You Will Do The Fluid Mechanics and Solid Mechanics group (T-3) of the Theoretical Division is seeking a highly motivated and productive postdoctoral candidate to contribute to the development and application of advanced computational models for manufacturing processes, with an emphasis on solidification in metals and alloys and large-scale simulation on emerging exascale architectures. Research activities may include the enhancement of phase-field models for microstructure evolution, grain evolution and segregation physics; continuum-scale fluid and solid mechanics modeling; development and application of AI/ML methodologies to integrate experimental and simulation data for manufacturing-process optimization; and numerical implementation and algorithm development within existing finite element codes. Collaboration with experimentalists will help facilitate calibration and validation of new models and enhancements. A successful applicant will engage in frequent communication of accomplishments with the primary mentor, contribute their expertise to technical discussions, fulfill technical goals, and satisfy required deliverables, such as codes, models, and expertise in the form of LANL reports, peer-reviewed publications, presentations, and software; and will agree to and follow LANL safety and security procedures.
