Postdoctoral Researcher (PREP0002184)

This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Research Title:
Postdoc in Light-Scatter Nanoscopy of Gene Delivery Particles

The work will entail...

Key responsibilities will include but are not limited to:

  • Integration and automation of hardware components, such as lasers, detectors, and optics, to develop a robust and user-friendly light scattering microscope for nanoparticle characterization.
  • Optimizing imaging parameters and data acquisition protocols to enhance measurement accuracy and efficiency.
  • Building optical models of gene delivery particles and nanoscopy instruments.
  • Collaborate with researchers and engineers to develop innovative algorithms for data analysis and interpretation.
  • Conduct experimental investigations to validate instrument performance, characterize particle physical characteristics and heterogeneity, and evaluate the impact of particle heterogeneity on gene delivery efficacy.
  • Publish research findings in peer-reviewed journals and present at conferences and workshops.


  • A PhD in Physics, Optics, Biophysics, or a related field.
  • Less than 5 years of relevant post-PhD experience.
  • Experience with optical imaging and/or microscopy,
  • Experience building, designing, and/or modifying scientific instrumentation.
  • Some familiarity with optical models of particle light scatter and/or optical instruments.
  • Programming experience with Python, MATLAB, or similar.
