Her research interests include transnational disparities related to women’s rights, water politics, urbanization and the environment. Dr. O’Leary is responsible for the design, collection and analysis of results from fisher interviews and associated elements related to how subsistence fishers differ from other fishing-oriented stakeholder groups.
Patrick Schwing, PhD
Patrick Schwing, PhDGeoscientist
Dr. Schwing’s research addresses societally relevant and globally significant issues including land-use development impacts, deep sea mining, oil spills, and the distribution and impacts of microplastics on marine systems. He utilizes sedimentological, radiochemical, micropaleontological, and biogeochemical tools to document the changing structure and function of benthic and planktic ecosystems. Dr. Schwing is an assistant professor at Eckerd College, a courtesy research associate at USF’s College of Marine Science, and is also involved with several international, collaborative projects. Dr. Schwing and the Eckerd College group are responsible for overseeing sediment sampling activities and developing chronologies of pollution by various CECs and CKCs over time.
