Research

My research focuses on occurrence, effects, and public knowledge of pharmaceutical and personal care products (PPCPs) in the marine environment. For my dissertation, I completed three research studies in the field, lab and community to investigate these topics. First, I examined PPCP accumulation in organisms placed near and far from wastewater sources in locations with low human populations in Oregon and Washington. Second, I conducted a lab experiment to determine effects of mixtures of PPCPs in coastal wastewater effluent on organism health. Lastly, I used surveys and interviews with pharmacy customers and pharmacists to determine leftover drug disposal behaviors and recommendations.
