Postdoc Research Associate - Nutrient Recovery and Water Reuse
Iowa State University
Ames, Iowa
Full-Time
Competitive
OfficeAssociate
Summary of Duties and Responsibilities:
The Postdoctoral Researcher will work closely with BEI Research Scientists to conduct research on nutrient recovery and recycling from cattle feedlot lagoon water using biochar-, clay mineral-, and woodchip-based filtration systems. This work will focus on developing and evaluating sustainable nutrient recovery technologies that enhance nitrogen, phosphorus, and potassium retention, reduce nutrient losses, and support circular agricultural systems.
The Postdoctoral Researcher will design and carry out laboratory, greenhouse, and column studies to investigate adsorption, desorption, nutrient cycling, and nutrient transport processes within engineered sorbent systems. Responsibilities include characterizing lagoon water and sorbent materials (e.g., biochar, clay minerals, woodchips, and nutrient-enriched media) using chemical and spectroscopic techniques, evaluating nutrient recovery and release efficiencies, and assessing impacts on soil health, water quality, and environmental sustainability.
This role also involves supporting the development and evaluation of proof-of-concept nutrient recovery systems for feedlot operations in collaboration with industry partners and stakeholders. The Postdoctoral Researcher is expected to work independently, contribute to interdisciplinary team efforts, mentor students as appropriate, and disseminate research findings through peer-reviewed publications, conference presentations, stakeholder engagement, and sponsor reports.

Department/Program & College Description:
Iowa State University’s Biorenewables Research Laboratory building is a visible “front door” to its many diverse and broad-reaching programs in biorenewables. The 70,000 sq. ft. facility, completed in 2010, provides affiliated faculty and staff a physical environment that promotes interdisciplinary, systems-level research and collaboration, including laboratory, meeting and teaching space for both graduate and undergraduate students. Construction was made possible through an appropriation from the state of Iowa. The Biorenewables Research Laboratory comprises about one-third of the Biorenewables Complex, which is also home to the Department of Agricultural and Biosystems Engineering.
