Ph.D., Duke University


Marney Pratt earned her doctorate in biology from Duke University.

When she was young, Pratt spent summers in Maine playing in a freshwater lake, which likely began her love of ecology and all things aquatic. During college, graduate school and postdoctoral work, her research focused in the field of biomechanics and physiological ecology in marine intertidal organisms, including red algae, bryozoans, nudibranchs and sea stars.  Since joining the Smith College Department of Biological Sciences, Pratt has started exploring local ecological and environmental issues in her teaching and research. In particular, she is involved in research monitoring the health of the Mill River using freshwater macroinvertebrates to assess how Smith College’s sediment management of Paradise Pond might influence the river. She currently teaches several laboratory sections of Biodiversity, Ecology, and Conservation and Animal Physiology. In both courses, she uses course-based research to help students learn through authentic research experiences.
