Isla S. Castañeda

Isla S. Castañeda is an Associate Professor with a joint appointment between the Department of Geosciences and the Commonwealth Honors College at the University of Massachusetts Amherst. Her research is centered in the field of molecular paleoclimatology, where she applies organic geochemical and isotopic proxies to reconstruct past climates and environmental conditions. She is affiliated with the UMass Amherst Biogeochemistry Laboratory and conducts interdisciplinary research spanning Earth, Geographic, and Climate Sciences.

Research Interests: Her work focuses on utilizing biomarkers—molecular fossils preserved in geological materials—to investigate paleoclimate and paleoceanography. Key areas include the use of plant leaf waxes (such as n-alkanes, n-alkanoic acids, and n-alkanols) to infer past vegetation (C3 vs. C4 plants), hydrological changes, and temperature reconstructions. She is actively involved in refining and developing new geochemical proxies for more accurate paleoenvironmental reconstructions.

The absence of listed publications in the provided text prevents analysis of article trends. Similarly, no scientific awards or formal advisees are mentioned in the available information.

Advising and Grants: While specific students or grant funding are not detailed in the text, her role in the Commonwealth Honors College suggests involvement in mentoring and supervising undergraduate research. Her research program likely involves extramural funding, particularly given her laboratory-based work in biogeochemistry, though no grants are explicitly referenced.

Laboratory and Research Team: Dr. Castañeda is associated with the UMass Amherst Biogeochemistry Laboratory, where research on sedimentary organic matter from archaea, bacteria, and eukarya is conducted. Her team investigates contributions from the three domains of life to better understand past environmental dynamics.
