Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely detected in coastal and estuarine systems. Due to their chemical stability and resistance to degradation, PFAS can accumulate in water, sediments, and biota, raising concerns about long-term ecosystem and human health impacts. Understanding the processes that control PFAS transport and fate in dynamic environments is critical for predicting exposure risks.

Our research investigates how environmental stressors influence the movement and distribution of PFAS across coastal and estuarine gradients. This work aims to identify the key drivers controlling PFAS transport between water and sediments.

Microplastics are an emerging contaminant in agricultural systems, with growing concern over their presence on fresh produce and potential implications for human health and food safety. Our research focuses on understanding how microplastics interact with leafy vegetables and how common agricultural and post-harvest practices influence their persistence.

Our project investigates microplastic contamination on widely consumed leafy greens, including romaine lettuce, iceberg lettuce, and spinach. By combining field-relevant sampling with laboratory analysis, we aim to better understand the pathways through which microplastics adhere to and interact with plant surfaces.
