Elsa is currently the chair of the Fish Passage Steering Committee and has been working as a Research Associate at the Museum of Comparative Zoology at Harvard University. she conducts research on fish locomotion and behavior, particularly swimming kinematics during high-speed locomotion. She is also a senior research fellow at the US Geological Survey’ S.O Conte Research Center, where she applies her expertise to lead projects on fish movement ecology and fish passage at dams and other riverine barriers, using advanced telemetry and statistical techniques. Her work includes species such as Atlantic salmon, sturgeon, eel, and sea lamprey, as well as a variety of native freshwater species. She is interested in fundamentals of fish locomotion as well as in developing biological criteria for selective passage designs at barriers, which allows native species to access upstream habitats while impeding movements of non-native, invasive species.
