Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.
Organizational 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.

The Imaging and Microscopy Program at NSLS-II operates the world-leading scanning probe microscopy (HXN, SRX, TES) and transmission X-ray microscopy (FXI) beamlines, and two additional beamlines (CDI and SXN) are under construction. The Imaging and Microscopy Program provides a suite of comprehensive research tools for new scientific discoveries and breakthroughs in critical areas.

Position Description

The NSLS-II is seeking an exceptional Postdoctoral Research Associate to join a research effort on developing an advanced coherent X-ray scattering method and commissioning a novel machine-learning-based workflow for high-throughput microelectronics metrology. The selected candidate will work with a team of scientists and technical staff within the Imaging and Microscopy Program, utilizing the world-leading expertise in X-ray imaging at NSLS-II and in collaboration with the researchers at the Center for Functional Nanomaterials (CFN) and the Computational Science Initiative (CSI).

Essential Duties and Responsibilities:

  • Develop a coherent X-ray scattering workflow for high-throughput, high-spatial-resolution microelectronic metrology.
  • Perform coherent scattering simulations and experiments, and incorporate machine-learning methods to optimize the metrology workflow.
  • Collaborate with CFN scientists to design and fabricate test structure.
  • Present results to peer-reviewed journals and conferences.

Position Requirements
