Postdoctoral Fellow; PREP

General Description

Salary: $82,000-$89,000 a year

PREP Research Associate

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.

Material Flammability Testing and Modeling

U.S. Citizen Preferred

The fire modeling community is working to predict material flammability behavior quantitatively (e.g., ignition, burning rate, fire growth). State-of-the-art fire models require input parameters (material properties) that describe combustible solids' decomposition reaction mechanism (and associated kinetics and thermodynamics) and relevant heat/mass transport properties.

To address this need, the NIST Fire Research Division has been developing experimental and analytical tools to calibrate these material properties and validate their ability to predict flammability response across a range of configurations/scales (i.e., mg-scale thermal decomposition, g-scale gasification/burning, and flame spread over panels between 0.5 m and 2.5 m tall).

Working with the project leader, the researcher will develop and then lead the execution of experiments associated with the following tasks.

• Developing a material flammability database that maintains the tools (experimental and analytical), measurement data (for model calibration and validation), and material property sets necessary to quantitatively predict material flammability behavior (e.g., ignition, steady burning, and fire growth).
• Conduct and analyze the data from bench to full-scale thermal and fire property tests for fire model calibration and validation.
• Produce and present publications on research findings.

• Assisting in the development, implementation, and leadership of a research plan to quantify fire growth rate, flame structure, condensed-phase response, and mass loss & heat release rate of combustible solids burning at the intermediate scale (emphasis on materials that deform; e.g., due to melt flow or charring/smoldering).
• Applying and advancing state-of-the-art techniques to quantify the mechanisms controlling material flammability; iterative development and implementation of analytical tools to process these results.
• Development and execution of plans for transferring NIST research through meetings, workshops, and conferences; preparing and presenting measurement results (oral presentations and written reports).

• PhD in Engineering (fire protection, materials science, mechanical), Chemistry, Physics, or a related field.
• 2+ years of relevant lab experience (i.e., experimental design and testing).
• Excellent oral and written communication skills.
• Excellent time management and organizational skills.
• Proficiency in programming/data analysis tools (e.g., Excel, MATLAB, Python, R).
• Ability to work independently and as part of a team to learn new activities and skills.
• Ability and enthusiasm to help lead early-career researchers as part of a research team.

Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID-19 vaccine. The COVID-19 vaccine does not apply to positions located in the State of Florida. We still require all faculty, staff, and students to receive the seasonal flu vaccine. Exceptions to the COVID and flu vaccine requirements may be provided to individuals for religious beliefs or medical reasons.

Requests for an exception must be submitted to the JHU vaccination registry. This change does not apply to the School of Medicine (SOM). SOM hires must be fully vaccinated with an FDA COVID-19 vaccination and provide proof of vaccination status. For…
