Dr. Katrina Pagenkopp Lohan is a parasite ecologist and head of the Coastal Disease Ecology Laboratory at the Smithsonian Environmental Research Center. Her research examines the ecology of parasites and infectious disease in coastal waters and how humans alter these interactions. She is also an avid reader, long distance runner, and the mother of two tenacious toddlers.
Parasites have profound impacts on individuals, populations, and ecosystems, by affecting the transfer of energy through food webs, regulating populations, promoting evolution, and causing infectious disease. She primarily studies parasites that infect commercially important shellfish and ecosystem engineers (e.g., seagrasses), whose loss would be devastating to an array of stakeholders. More specifically, her research examines how parasites and the diseases they cause impact ecosystems, and how ecosystems impact parasites and the diseases they cause. This research falls into four main themes: 1) Parasite Biogeography: Shifting Baselines, 2) How Biodiversity Impacts Disease in Aquatic Systems, 3) Impacts of Disease and Parasites on Ecosystem Function, and 4) One Health in the Coastal Zone.
