Post-Doctoral Associate: Resource Recovery and PFAS Remediation
Job opening: 348817
Temporary/Full Time position/Open until filled
About the Job:
Over thirty-five million tons of food waste are disposed of in the US annually, representing a potentially utilizable source of nutrients and energy. However, contamination of food waste with poly- and perfluoroalkyl substances (PFAS) could potentially limit applications to sustainably recover these resources.
The Natural Resources Research Institute is seeking a postdoctoral researcher to join an interdisciplinary team and lead an applied research project to develop modern technologies to sustainably recover nutrients and energy from food waste. The position will be based in Dr. Bridget Ulrich’s Environmental Chemistry Laboratory at NRRI Duluth and involve collaboration with the NRRI Biomass Conversion Laboratory as well as Dr. Bo Hu’s Bioprocessing group at the College of Food and Agricultural Sciences (CFANS) in St. Paul, MN. The project is funded by MnDRIVE Environment, which seeks to advance industry and conserve the environment in Minnesota. Research will be conducted in collaboration with Ramsey/Washington Recycling and Energy (R&E), which seeks to enhance public health and the environment by creating value from waste through partnerships.
The postdoctoral researcher will lead the design and implementation of an experimental plan to evaluate the fate of PFAS during treatment of food waste by anaerobic digestion and hydrothermal liquefaction. They will also perform target and nontarget analysis of PFAS in food waste by liquid chromatography quadrupole time-of-flight mass spectrometry (LC- QTOF-MS) and contribute to mentorship of students working on PFAS-related projects.
They will also facilitate communication with project partners and contribute to dissemination and technology transfer activities. Initial experiments will be performed at the laboratory scale, with the possibility of increasing to pilot- or demonstration-scale the following year, depending on funding availability. The postdoctoral researcher will have the opportunity to contribute to proposal preparation and set the direction of the applied research.
The position is for one year and can be renewed for a second year with satisfactory progress. Additional extension of the appointment may be considered depending on availability of funding. Applicants should note their availability in their cover letter. A start date in fall 2022 is preferred but exceptional applicants with later availability are encouraged to apply.
