The successful applicant will work with PI Manuel Scharrer, Co-PI Fuhar Dixit, and an industry partner on experimental studies aimed at understanding and optimizing selective REE separation. The research will investigate how thermodynamic and chemical properties of REE-bearing phases and solutions influence precipitation and REE fractionation, with the goal of identifying conditions that can be applied to increasingly complex and realistic feed compositions.

Research activities will include laboratory synthesis, precipitation experiments, calorimetric and other thermodynamic measurements, structural and elemental characterization, and quantitative analysis of experimental data. The researcher will use experimental results to develop and refine thermodynamic interpretations and models and to guide experimental optimization. The researcher will interact with project industry partners as appropriate to evaluate experimental results and their relevance to realistic REE processing conditions. The researcher will also work closely with a second postdoctoral researcher focused on engineering and prototype development under Co-PI Dixit, with the two research efforts informing one another throughout the project.

The postdoctoral researcher will supervise undergraduate researchers involved in experimental research and characterization. The project is planned as a two-year effort. The position is initially offered for up to one year, with the expected renewal for a second year based on performance and continued funding.

The University of Tennessee, Knoxville, has shaped leaders, changemakers, and innovative thinkers since its founding in 1794. The university is home to more than 38,000 students and 10,000 statewide employees-the Volunteers-who uphold the university's tradition of lighting the way for others through leadership and service.

UT Knoxville offers over 900 programs of study across 14 degree-granting colleges and schools. As Tennessee's flagship land-grant university, its footprint spans the entire state. The university holds the highest Carnegie classification for research activity and has deep partnerships with industry leaders and the US Department of Energy's largest multidisciplinary laboratory, Oak Ridge National Laboratory.

The Knoxville campus serves and recruits for UT Knoxville, including the Institute of Agriculture and the Space Institute, as well as the UT Institute of Public Service.

UT Knoxville considers its employees its number one asset. With values that focus on work-life balance, compensation, and innovation leadership, all Vols are supported to advance professionally. Employees have access to career development and coaching, continued education, and an extensive list of development and training possibilities. The Volunteer employee experience implements structures and practices to attract and retain top-tier talent, fostering a strong staff community and supporting a culture of involvement and engagement for everyone.

The university holds a strong commitment to its land-grant mission of learning and engagement, with a tradition of service and leadership that carries that Volunteer spirit throughout the state and around the world. It has been ranked nationally as "Best Employer for New Graduates," "One of America's Best Large Employers," and "Best Workplace for Women," and has been designated as "Best Place for Working Parents" by Forbes Magazine.
