Postdoctoral Research Associate - Organic and Critical Minerals Separation Chemist

Overview:

We are seeking a highly motivated Postdoctoral Research Associate in Organic Chemistry and/or Critical Materials Separation Science to develop next-generation ligands and functionalized sorbents for the selective extraction and recovery of gallium (Ga), germanium (Ge), and other critical minerals from complex zinc-processing feed stocks. The successful candidate will conduct organic synthesis, materials characterization, solvent extraction, and solid-phase separation studies to advance sustainable critical mineral recovery technologies.

This position resides in the Nanomaterials Chemistry Group in the Separations and Polymer Chemistry Section, Chemical Sciences Division, Physical Sciences Directorate, at Oak Ridge National Laboratory (ORNL).

As part of our research team, you will be responsible for delivering high impact research results to advance the work on Gallium and Germanium separations. You will be very closely working with specialists in synthesis, separations chemistry, radiochemistry, theory, spectroscopy, and materials characterization. This project will develop materials and processing technologies that will result in a transformational improvement in separation and recovery methods for Gallium and Germanium.
