Assistant Curator, Earth Sciences
Biography
Carla Rosenfeld is the assistant curator of Earth Sciences in the section of Minerals and Earth Sciences. Carla received her Ph.D. in Soil Science and Biogeochemistry from Penn State and a B.S in Chemistry from McGill University. She also worked as a postdoctoral fellow at the Smithsonian National Museum of Natural History Department of Mineral Sciences and University of Minnesota Department of Earth and Environmental Sciences.
Carla is an environmental biogeochemist whose research uses tools from mineralogy, geochemistry, and microbiology to study how pollutants and nutrients behave in the environment. Her research focuses on mining and other human-impacted environments and aims to understand plant-microbe-mineral interactions that influence bioavailability and mobility of metal contaminants. Carla’s work combines field- and lab-based investigations and she has projects studying microbial biominerals, their mechanisms of formation, and their role in bioremediation, as well as impacts of soil or sediment geochemistry on microbial ecology, and plant-microbe feedbacks on environmental processes.
