Job Details

Lawrence Berkeley National Lab's (LBNL) Materials Science Division has an opening for a Postdoctoral Fellow specializing in the theoretical modeling of structured light-matter interactions in the X-ray regime. This role focuses on developing and applying theoretical models to electronic, magnetic, and topological materials, particularly in support of collaborative experimental research. It is ideal for a scientist eager to work across disciplines, contribute to national user facilities, and push the boundaries of photon-based materials research.

What You Will Do:

• Theoretical development of materials models for electronic and magnetic structures from the atomic to the mesoscale.
• Theoretical development of X-ray interactions with materials for (focused) photon beams with orbital angular momentum.
• Collaboration with theory and experimental groups.
• Publishing and presentation of work in peer-reviewed formats and at national/international conferences.
• Contribution to group activities - presentation of active research, installation of software, teaching and training of junior personnel, scientific collaboration.
• Maintaining a collegial, healthy and safe work environment for self and others.

What is Required:

• PhD in Physics, Applied Mathematics, or a related discipline with a focus on theoretical modeling.
• Specific experience in quantum mechanics, light-matter interactions, structured/topological fields for both photons and spins/dipoles.
• Specific experience in the development of mathematical models for complex physical phenomena related to electronic structure, magnetism, vortices/skyrmions, etc.
• Specific experience in translating theoretical models to direct simulation and interpretation of experiment.
• Track record of collaboration with experimental groups.
• Publication record in peer-reviewed literature with multiple papers as primary author and experience in submission and revision of scientific publications.
• Skilled in scientific writing and presentations, public speaking and scientific communication, graphical representation of complex data, and translation of scientific concepts across disciplines.
• Knowledge of programming languages and scientific computing environments: fortran or C/C++, python, linux.
• Experience in the use of data science and analysis techniques for complex data sets, especially with python.

Desired Qualifications:

• Experience in software development practices, version control, user support.
• Experience with tight-binding, density functional theory, and many-body condensed matter theory and associated software.
• Experience in machine learning applied to scientific research.

Notes:

• For full consideration, please apply by September 12, 2025.
• Appointment Type: This is a full time, exempt from overtime pay (monthly paid), 2 year (benefits eligible), Postdoctoral Fellow appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs. You must have less than 3 years of paid postdoctoral experience.
• Salary Information: This position is represented by a union for collective bargaining purposes. Postdoctoral Fellow positions are paid on a step schedule per union contract and salaries are predetermined based on postdoctoral step rates. Each step represents one full year of completed post-Ph.D. postdoctoral and/or related research experience. This position has a targeted monthly salary range of $7,987.00 - $8,921.00 and is expected to start at $7,987.00 or above.
• Background Check: This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
• Work Modality: Work will be primarily performed at:Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA. A REAL ID or other acceptable form of identification is required to access Berkeley Lab sites (for more information click here).
