Postdoctoral Research Associate Advanced X-ray Imaging for Microelectronics

Job ID JR100727 Date posted 11/22/2023

ORGANIZATION OVERVIEW

As one of the newest, most advanced synchrotron light sources in the world, National Synchrotron Light Source II (NSLS-II) enables its growing research community to study materials with nanoscale resolution and exquisite sensitivity by providing cutting-edge capabilities. This facility is open to users from academia and industry. Its operations are at a time when the world enters a new era with a global economy fueled largely by scientific discoveries and technological innovations.

POSITION DESCRIPTION

The NSLS-II seeks an exceptional Postdoctoral Research Associate to join a research effort on developing ptychographic imaging using reflection geometry.  The goal of this technique development is to enhance the measurement sensitivity to vertical interfacial structure, with a substantial potential application for microelectronics (i.e., characterizing EUV lithography structures).  The research will be conducted by performing simulations (kinematical and dynamical) and experiments while incorporating the latest machine-learning algorithms (to take advantage of the microelectronic sample's prior knowledge and to achieve super-resolution). The selected candidate will work with a team of scientists from NSLS-II, CFN (Centers for Functional Nanomaterials), CSI (Computational Science Initiative), and IO (Instrumentation Division), plus other postdoctoral researchers who are working on different aspects of the project (i.e., preparing appropriate test patterns, and performing coherent scattering characterization).  Furthermore, as a member of the Imaging and Microscopy Program, the successful candidate will collaborate broadly with the other members, leveraging their expertise in advanced x-ray imaging (i.e., ptychography, tomography, etc.).

Essential Duties and Responsibilities: 

• Develop ptychographic imaging using reflection geometry by performing simulations and conducting experiments.
• Explore opportunities for utilizing prior knowledge of the sample to achieve faster or more robust results.
• Collaborate with researchers at NSLS-II, CFN, CSI, and IO, taking advantage of their expertise to achieve the research goal.
• Present results to peer-reviewed journals and conferences.

Required Knowledge, Skills, and Abilities:

• Ph.D. in Computer Science, Physics, Material Science, or related discipline
• Demonstrated expertise in ptychography
• Demonstrated experience in computational programming 
• Excellent oral and written communication skills
• Excellent publication or presentation records in the related areas
• Ability to work independently as well as effectively in a collaborative team environment for solving scientific problems

Preferred Knowledge, Skills, and Abilities:

• Demonstrated experience in X-ray reflectivity and dynamical scattering
• Demonstrated experience in ptychographic data analysis
• Demonstrated experience in Python programming (either via publications or software)
• Knowledge of machine-learning algorithms for imaging application

Other Information:

BNL policy requires that after obtaining a PhD, eligible candidates for research associate appointments may not exceed a combined total of 5 years of
relevant work experience as a post-doc and/or in an R&D position, excluding time associated with family planning, military service, illness or other life-changing events.

Brookhaven National Laboratory and the Energy and Photon Sciences Directorate are committed to your success. We offer a supportive work environment and the resources necessary for you to succeed.

Brookhaven Laboratory is committed to providing fair, equitable and competitive compensation. The full salary range for this position is $68400 - $113250 / year.  Salary offers will be commensurate with the final candidate’s qualification, education and experience and considered with the internal peer group. Position level & salary will be commensurate with experience and qualifications

Brookhaven employees are subject to restrictions related to participation in Foreign Government Talent Recruitment Programs, as defined and detailed in United States Department of Energy Order 486.1A. You will be asked to disclose any such participation at the time of hire for review by Brookhaven.
