Biotransformation of PFAS in Contaminated Environments
Lisa Alvarez-Cohen, Professor
Civil and Environmental Engineering
Applications for Spring 2025 are closed for this project.
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals used in various industrial and consumer products, including Aqueous Film Forming Foam (AFFF), widely used since the 1960s for firefighting. Due to their persistent, bioaccumulative, and toxic nature, PFAS pose significant environmental and health risks. Despite their widespread use, the biotransformation of PFAS, especially under anaerobic and redox-specific conditions, remains poorly understood. This project aims to examine the impact of redox conditions on the biotransformation of PFAS precursors and their migration in contaminated environments, with a focus on the potential for groundwater and drinking water contamination.
Role: The successful candidate will be responsible for sampling, sample preparation, and maintaining microcosms under various redox conditions. They will assist with data analysis, monitor PFAS degradation and mobility, and support the operation of different instruments to track redox conditions.
Qualifications: 1. A background in environmental engineering, chemistry, or a related field (desired).
2. A commitment of more than 6 hours per week (required).
3. Wet lab experience (desired).
4. The ability to follow protocols, think independently, and meet tight deadlines (required).
Day-to-day supervisor for this project: Leyan Peng, Graduate Student
