Daniel Enrique Ibarra

Miller Research Fellow and President's Postdoctoral Fellow, Earth and Planetary Science, University of California, Berkeley

Welcome to my website!

I am a geochemist and climate scientist working on the water and carbon cycles in terrestrial environments. My work includes studying the response of past and present terrestrial landscapes to changes in climate using modeling approaches, geochemical measurements, and field observations. Broadly speaking, I am interested in the role that Earth's continents play in modulating habitable surface conditions over geologic time, and in using sediments to reconstruct past changes in weathering and hydrologic fluxes over Plio-Pleistocene to Phanerozoic timescales.

I am a postdoc at UC Berkeley in Earth and Planetary Sciences supported by a Miller Institute Research Fellowship and President's Postdoctoral Fellowship. Previously, I was a postdoc in Geological Sciences at Stanford University, and received my Ph.D. (Earth System Science), M.S. (Geological & Environmental Sciences) and B.S. (Civil & Environmental Engineering (Atmosphere/Energy) and Geological & Environmental Sciences) degrees from Stanford University.

Starting in 07/2021 I will be an Assistant Professor at Brown University appointed in the Department of Earth, Environmental and Planetary Sciences and the Institute at Brown for Environment & Society. Prospective students and postdocs are encouraged to contact me directly.

Research Interests

Investigating the influence of plants, geology and climate on nutrient and chemical fluxes in freshwater systems, including quantifying patterns of covariation between solutes and hydrology.

Developing new modeling frameworks for investigating the response of watersheds and lake systems to climatic forcings.

Documenting past changes in climate using terrestrial geologic records as indicators of hydroclimate change to test the robustness of climate model simulations used for future projections.

Advancing new analytical geochemical techniques to infer how the atmosphere, water cycle and land surface reflect ongoing and past changes in climate.

Current work includes:

- Reconstructing the Plio-Pleistocene and Cenozoic water cycle in the western United States using lake deposits, including triple oxygen isotopes and carbonate clumped isotopes, and modeling approaches.

- Quantifying weathering and nutrient fluxes from ultramafic catchments in the Philippines.

- Integerogating Cretaceous hothouse climate changes using terrestrial sediment cores in northeast China.

- Investigating the triple oxygen isotope systematics of the ocean, altered igneous rocks, and deep-sea sediments.
