About Samantha

Dr. Weintraub is the lead Biogeochemist for the Terrestrial Observation System (TOS). She oversees collection protocols and data quality efforts related to soil and sun-lit plant foliage sampling, and collaborates with other NEON scientists on litterfall and fine root sampling data and workflows. She is the technical lead for the NEON data products that provide direct measures of soil and vegetation chemistry and stable isotopes, including soil nitrogen transformations. Dr. Weintraub works closely with colleagues to integrate sampling efforts with the NEON Airborne Observation Platform (in the case of sun-lit foliage sampling) and microbial measurements (in the case of soil sampling).

Dr. Weintraub’s research focus is on carbon and nutrient cycling in plants, soils, and watersheds. Her work investigates the controls on long-term ecosystem development trajectories as well as short-term biogeochemical dynamics in the context of climate and land-use change. She has worked in diverse ecosystems, from tropical rainforests to high mountains and urban landscapes, and has strong experience using light stable isotopes to reveal new ecological insights. She received her B.S. from the University of California Berkeley, her Ph.D. from the University of Colorado Boulder, and conducted postdoctoral research at the University of Utah before joining NEON.
