Dr. Jiuyuan Wang
Agouron Postdoctoral Fellow
Jiuyuan Wang is an isotope geochemist. He is broadly interested in sedimentary geochemistry and geobiology, with particular focus on the co-evolution of life and environment, climate and its feedbacks on seawater chemistry, as well as the fundamental behaviors of isotope systems. He is working on the MRV of the enhanced weathering technique in the group.

Dr. Tim Jesper Suhrhoff
Postdoctoral Fellow
I study how rocks break down naturally and how we can speed it up to suck more CO2 out of the air. I use fancy isotope stuff to see how rocks behaved during ancient climate changes. Right now, I’m playing with soil, water, and models to see how much CO2 we can trap in our enhanced weathering experiments.

Brian Beaty
PhD candidate
I am broadly interested in the coevolution of life, climate, and chemical cycles across Earth history, and how the geochemical composition of sedimentary rocks captures these dynamics. Current projects include reconstruction changes in ocean pH across ancient global warming events with boron isotopes, as well as changes in chemical weathering on land with lithium isotopes.

Tom Reershemius
PhD candidate
My work focuses mostly on carbon dioxide removal through enhanced rock weathering (ERW). I use trace metal analysis and other geochemical tools to track mineral weathering rates in laboratory and field experiments, and look at how this impacts ERW as a viable negative emissions technology. More broadly, I’m interested in examining questions about the interplay of the carbon cycle, oxygenation and climate change through Earth history.

Jingjun Liu
PhD candidate
As an astrobiologist, I am interested in the co-evolution of life on Earth and Earth’s atmosphere, particularly in the Precambrian. For the past 3 years, I have been developing a new isotopic photochemical model, a new conceptual paradign and a new proxy for the triple oxygen isotope system, the best system we have to track the Precambrian pO2 and pCO2 due to its mass independent nature. I am currently also working on publishing our major discovery onto a mechanism of Nature that could shape the evolution of surface life for more than 3 billion years.

Gavi Welbel
Research Assistant
I’m interested in approaches to land management that mitigate climate change, increase resilience, and support ecosystem health. My research is focused on enhanced mineral weathering in agricultural settings, and specifically focused on field trials based at Zumwalt Acres.
Benjamin Mousseau
Undergraduate research assistant
Benj just joined the group in January 2023 and is super excited to be helping out! He is supporting the wastewater treatment plant carbon capture project by helping to characterize particle size distributions in the powdered-up rocks that will be dissolved in the wastewater.
