Postdoctoral researcher
The growing demand for critical minerals has highlighted the need for a more diverse and secure supply
chain. The traditional linear model of resource extraction, processing, use, and disposal is subject to
supply chain risks and results in a significant loss of critical minerals from the economy. As a result, there
is increasing interest in transitioning to a more circular economy, where materials are recovered and
reused at the end-of-life through recycling and other strategies. This shift has significant implications for
the management of electronic scrap (e-scrap), which is a valuable source of critical minerals such as rare
earth elements, lithium, and other key materials.
Current e-scrap recycling practices involve device shredding and separation of bulk materials (steel,
aluminum, plastics, etc.). Many critical minerals and precious metals are not recovered in current
processes, and to do so requires an improved understanding of where they end up in the recycling
system. In this study, we’re aiming to characterize the bulk separated material streams provided by e-
scrap recyclers to understand elemental compositions and identify opportunities for recycling system
improvements. In that effort, we seek a post-doctoral researcher with wet chemistry experience to
support laboratory work, data analysis, and information dissemination. The researcher will work with an
interdisciplinary NIST team in applying multiple analytical methodologies, including neutron activation
analysis, XRF, and ICP-MS and OES, among others, as well as document and report findings. The ideal
candidate would have prior experience working in laboratory setting with a good understanding of
laboratory procedures, laboratory safety, and knowledge of critical mineral analyses.
