Postdoctoral Fellow; PREP

General Description

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). 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.

Materials science and rheology of complex polymeric and composite materials

• Design and execute rheological characterization of complex fluids and soft solids
• Lead thermal and thermomechanical characterization
• Characterize and model reactive/curing systems
• Build structure-property insights through multimodal characterization
• Author publications and present research to stakeholders

U.S. Citizen Preferred

• Ph.D. in polymer science, materials science, chemical engineering, or a related discipline.
• Expertise in rheology, including advanced techniques such as orthogonal superposition rheology and large amplitude oscillatory shear rheology.
• Experience with thermal analysis (DSC and at least one of DMA/TGA/TMA/CTE/thermal conductivity methods), including calibration/validation.
• Solid background in cure kinetics, chemorheology, and polymer physics.
• Experience with additive manufacturing (extrusion-based and vat photopolymerization).
• Strong quantitative/data skills (Matlab/Python/Origin/JMP) for processing large datasets, fitting models, and producing publication-quality figures.
• Track record of technical writing (peer-reviewed papers, technical reports, SOPs) and communicating results to mixed audiences.
• Demonstrated ability to lead projects, mentor students/postdocs, and coordinate cross-functional collaborations.
• Ability to work on-site in a laboratory setting in Gaithersburg, MD and meet all safety/training requirements.
