Daniel E. Ibarra

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, 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 Filipino-American geoscientist from Bozeman, Montana, though I was born in Europe and grew up as an expatriate in Hong Kong. In 2020 I co-founded the Asian Americans and Pacific Islanders in Geosciences organization. Additionally, I was a founding Advisory Council member of EarthArXiv, a preprint server for the Earth and Planetary Sciences, in 2017, and since 2019 serve as an Associate Editor for the American Journal of Science (Yale University/HighWire Press), an international Earth science journal, since 2021 serve as an Associate Editor for All Earth (Taylor & Francis) and since 2022 am on the Earth science Editorial Board for Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences. My international collaborations include the International Continental Drilling Program’s ongoing terrestrial drilling in the Songliao Basin, northeast China, and participating in the Republic of Philippines’ Balik Scientist Program in 2019 at the University of the Philippines, Diliman.

I am an Assistant Professor at Brown appointed in the Department of Earth, Environmental and Planetary Sciences (DEEPS) and as a Fellow in the Institute at Brown for Environment & Society (IBES). My full Brown profile and CV are available here:

My current work includes:

  • Reconstructing the Plio-Pleistocene and Cenozoic water cycle in the western United States and Tibet using lake deposits and hydrothermal systems, including the use of triple oxygen isotopes and carbonate clumped isotopes, as well as modeling approaches.
  • Quantifying modern weathering and nutrient fluxes from ultramafic catchments in the Philippines.
  • Interrogating 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.
