Soft X-ray Reflection Microscopy Postdoctoral Fellow at Lawrence Berkeley National Laboratory



The Advanced Light Source Division at Lawrence Berkeley National Laboratory (Berkeley Lab) is seeking a Soft X-ray Reflection Microscopy Postdoctoral Fellow. The objective of this postdoctoral position is to develop reflection microscopy of condensed matter materials using soft x-rays. You will be responsible for the development, implementation and testing of the technique with the goal of implementing a newly developed full-frame method called randomized probe imaging (RPI) in reflection.

The Advanced Light Source is a U.S. Department of Energy (DOE) Office of Science national scientific user facility. The ALS has been a global leader in soft x-ray science for more than two decades and is currently undergoing a large-scale upgrade (ALS-U) that will endow the facility with state-of-the-art x-ray capabilities. It's an exciting time to join our team!

What You Will Do:

·   Develop the instrumentation and data analysis for a reflection soft x-ray microscopy technique. 

·   Perform soft X-ray microscopy experiments (holography and/or ptychographic-based) at BLs, 12.0.2 and/or 7.0.1

·   Perform image analysis in Python or similar by writing codes or using established software. 

·   Collaborate well with other research teams and scientists.

·   Publish work in peer-reviewed scientific literature.

·   Present work at national meetings and at regular group meetings.

·   Contribute positively to the active research culture.

·   Work in a safe and healthy manner consistent with EH&S guidelines.

·   Respect diversity and strive for inclusivity in interactions with others.

What is Required:

·   PhD in Physics, Chemistry, Materials Science, or equivalent.

·   Sound knowledge and keen interest in x-ray scattering, diffraction, or microscopy. 

·   Ability to safely perform independent hands-on work in an experimental endstation. 

·   Proficiency in programming for handling complex datasets, e.g. Python

·   Proven track record in disseminating research at conferences and in publications

Desired Qualifications:

·   Experience in ptychography or coherence techniques. 

·   Experience in condensed matter material systems (e.g. magnetic, ferroelectric, etc.)

·   Knowledge of x-ray resonant scattering and/or diffraction methods. 

·   Working knowledge of high vacuum practices.

·   This is a full-time, 2 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 3 years of paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.

·   This position is represented by a union for collective bargaining purposes.

·   The monthly salary range for this position is $6,936.00 - $7,747.00. Postdoctoral positions are paid on a step schedule per union contract and salaries will be 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 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.

·   This position is eligible for a hybrid work schedule - a combination of teleworking and performing work on site at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA. Work schedules are dependent on business needs. Individuals working a hybrid schedule must reside within 150 miles of Berkeley Lab.
