Postdoctoral Fellow (PREP0004192) Full-time

Postdoctoral Fellow

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may want to collaborate with researchers at academic institutions on specific projects of mutual interest and, therefore, requires those institutions to be recipients of a PREP award. The PREP program involves staff from a wide range of backgrounds conducting scientific research across various fields. Individuals in this position will perform technical work supporting the collaboration's scientific research.

Research Title: Infrared Microscopy for Microplastics Characterization (U.S. Citizens preferred)

The Material Measurement Laboratory of the National Institute of Standards and Technology is seeking qualified persons (U.S. Citizens preferred) to advance a novel quantum cascade laser (QCL) infrared (IR) microscopy technique for high-throughput measurement of size distribution and chemical identification of microplastic samples. The position will harness a groundbreaking QCL-IR imaging of microplastics in water by addressing nontrivial measurement problems due to the strong IR absorption by water and strong scattering contribution at <10 µm microplastics. The outputs of this work will help improve measurement assurance for microplastics characterization with less irregularity in sample preparation and more reproducibility in size quantitation. Working at NIST offers the rare opportunity to collaborate with world-class experts in a mission-driven environment, utilizing state-of-the-art microscopes to turn observations into reproducible science. It is a chance to leave a lasting legacy on the circular and champion sustainability by ensuring a foundation of sound measurement science.

Key Responsibilities Will Include But Are Not Limited To:

• Advance the instrumentation for high-throughput QCL-IR microscopy
• Collect and analyze IR hyperspectral images of microplastics
• Discuss progress and results with NIST staff
• Present results at internal meetings, and occasional meetings with external stakeholders
• Write papers based on method advancements and datasets collected

Qualifications

• Ph.D. degree in Chemistry, Physics, Polymer Physics, or a related field
• 2+ years of experience with IR microscopy
• Ability to analyze vibrational spectral data
• Strong oral and written communication skills
