Dr. Holzer's research focuses on rock weathering, soil formation, and carbon dynamics in the soils of agricultural and natural systems. Broadly, her work is driven by a desire to better understand weathering — the process of mineral transformations at the surface of Earth — and its connections to elemental cycling, hydrologic systems, and the broader biosphere. One of her major areas of study is the carbon dioxide removal potential of enhanced rock weathering in cropland soils. Other current topics of interest include rock-derived nitrogen release in terrestrial ecosystems and interactions between weathering and salinity in irrigated drylands.
