Cornell Faculty Member

Positions

Carmen Enid Martínez is a soil and environmental chemist and biogeochemist. My research and teaching foci are soil minerals, soil organic matter, reactions at the solid-solution interface, and their associated (biogeo) chemical processes. My aim is to gain a mechanistic understanding of soil transformations and processes that increase our science-based knowledge of managed and natural ecosystems.

research overview

  • The goal of my research program is to provide a fundamental understanding of the chemical and biogeochemical processes involved in the cycling of major (N, S, C, Fe, Al, Mn), trace (Zn, Cu) and toxic (Cd, Cr, Pb) elements present in terrestrial ecosystems. We use process-based measurements and state-of-the-art spectroscopic (e.g., XAS, FTIR, NMR), microscopic (e.g., TEM, SEM) and diffraction (e.g., XRD) methods to understand ecosystem element cycles and processes from the molecular to the field scale. Recent research topics include: molecular scale investigations of the interaction of organic carbon and nitrogen at mineral surfaces and biomolecular signature in soils with depth, trace metal biogeochemistry, and processes within Fe-N-organic matter coupled systems as influenced by redox condition.
