FAST-XAS Postdoc

Website Advanced Light Source (ALS)

Lawrence Berkeley National Lab’s (LBNL) Advance Light Source (ALS) Division has an opening for a FAST-XAS Postdoc to join the team.

In this exciting role, you will participate in a collaborative effort with scientists from the CXRO, TMF and MBIB to develop a new innovative soft X-ray characterization method at the ALS. The goal is to demonstrate a revolutionary scheme for soft XAS in an ultra-high-throughput fashion, so that the XAS spectra can be recorded under a single-shot of X-rays with wide spectral bandwidth. You will perform experiments to demonstrate the ultra-high-throughput screening for materials discovery, the measurement of multiple chemical sites simultaneously for chemical dynamics, and an experimental database for ML training for materials discovery.

What You Will Do:

  • Lead the FAST-XAS development with the LDRD collaborating scientists for the XAS and RIXS instrumentation, experimental planning, data acquisition and data analysis.
  • Participate in performing forefront scientific research in synchrotron experimental study of materials science, with emphasis on the use of soft x-ray absorption spectroscopy (XAS) and resonant inelastic soft x-ray scattering (RIXS) techniques and instrumentation.
  • Participation in implementation of RIXS spectrometer for soft x-ray spectroscopy experiments.
  • Participate in the experimental program at XAS and RIXS beamlines the associated endstations.
  • Collaborate with the scientists, engineers and technical support staff at the ALS to perform planned experiments.
  • Adherence to environment, safety, and health policies and procedures.
  • Disseminate experimental and research results via publications in refereed journals; present results via oral presentations at scientific meetings, conferences and peer reviews.
  • Commitment to safe working practices. Ensure that self and beamline users are trained in accordance with relevant ES&H regulations.
  • Maintain current knowledge of and implement applicable policies and regulations, including LBNL and ALS Conduct of Operations and Quality Assurance policies and procedures.

What is Required:

  • Demonstrated experience with synchrotron based soft x-ray spectroscopy techniques and instrumentation applied to the study of electronic properties of materials.
  • Solid knowledge of electronic structure and property and materials as well as a thorough understanding of characterization techniques and instrumentation.
  • Demonstrated experience to pursue new areas of materials and chemical science research involving sophisticated instrumentation including ultrahigh vacuum, x-ray photons and charged particle detection.
  • Experience in thin film deposition technology or liquid flow delivery (liquid jet or microfluidics).
  • Experience in computing, data acquisition and analysis, and machine learning.
  • Be independent, innovative and able to carry out an experiment from initiation to meaningful conclusion in collaboration with a team of scientists and technical support staff.
  • Effective oral and written communication skills.
  • Ph.D. or equivalent in Physics, Chemistry, Materials Science or Engineering.


  • This is a full-time 1 year postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than 4 years years of paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.ion:
  • This position is represented by a union for collective bargaining purposes.
  • Salary will be predetermined based on postdoctoral step rates.
  • 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 will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
