I am a biogeochemist and climate scientist working on the water and carbon cycles. This includes studying modern rivers and catchments, as well as the terrestrial geologic record (lakes, soils, and caves), to understand Earth system processes that link the biosphere, atmosphere, and lithosphere. The aim of this work is to gain a better understanding of how the Earth’s water and carbon cycles respond to forcings, including ongoing anthropogenic climate change. We are also working on the characterization and quantification of lithium deposits in lacustrine basins and enhanced weathering strategies for carbon dioxide removal. Our tools include geochemical measurements, field observations, reactive transport modeling, hydrologic modeling, and synthesis of climate model output.
I am a Filipino-American geoscientist from Bozeman, Montana. I was born in Europe and grew up 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. In 2019 I was a Republic of Philippines Balik Scientist at the University of the Philippines, Diliman.
Prior to Brown, at Stanford University, I received a dual BS degree in 2012 from the Civil & Environmental Engineering Atmosphere/Energy program and in Geological & Environmental Sciences (with honors), an MS in Geological Sciences in 2014 working with Kate Maher (Environmental Geochemistry), and a PhD in Earth System Science in 2018 working with Page Chamberlain (Terrestrial Paleoclimate). From 2019 to 2021 I was a Miller Institute and President’s Postdoctoral Fellow at UC Berkeley working with Daniel Stolper (Stable Isotope Geochemistry) and Don DePaolo.
At Brown I am appointed in the Department of Earth, Environmental and Planetary Sciences (DEEPS), working between the Climate & Environment and Geochemistry, Mineralogy & Petrology curricular groups, as a Core Fellow and Director of Diversity, Equity and Inclusion in the Institute at Brown for Environment & Society (IBES), on the Executive Committee for the Initiative for Sustainable Energy (ISE), and as the Inclusion, Diversity, Equity, and Accessibility lead for LunaSCOPE (Brown’s NASA SSERVI Team).

My current work includes:
- Reconstructing the Plio-Pleistocene and Cenozoic water cycle in the Philippines, western United States and Tibet using speleothems, 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.
