Description

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.

The Infrastructure Materials Group (IMG) is seeking a highly motivated Research Associate to be a part of the Next-Generation Building Standards initiative within NIST.

Degradation of reinforced concrete due to embedded steel corrosion remains a monumental challenge, with direct and indirect costs accounting for approximately 6% of the U.S. Gross Domestic Product.

Current building codes, testing standards, and common-practice heuristics, such as diffusion coefficient, depth of cover, and chloride per unit mass of cement, are inadequate for assessing the complex environmental factors and novel binder chemistries that most strongly affect structural service life.

To address this, the IMG "Assessing Steel Corrosion Risk in Innovative Cement Concretes" project aims to integrate advanced electrochemical characterization with species-transport modeling. We are seeking a highly motivated Postdoctoral Researcher with academic training and experience in corrosion science to develop new metrology standards specific to reinforced concrete structures, which are often in unsaturated conditions. The selected candidate will focus on measuring the precise rates of corrosion initiation and progression, ultimately providing
