Bullard Fellow Wyatt Oswald, an Associate Professor of Science at Emerson College in Boston, has been affiliated with the Harvard Forest for more than a decade. Working closely with Harvard Forest collaborators David Foster and Elaine Doughty, he analyzes lake-sediment cores to reconstruct past environmental changes.
During his Bullard Fellowship, Oswald has synthesized various types of paleoecological data from Cape Cod and the adjacent islands to study long-term changes in climate, vegetation, and fire. He chose to work at Harvard Forest for its "outstanding facilities and a strong tradition of using retrospective ecology to understand forest dynamics and inform conservation, management, and policy."
