Shuhei Ono

Professor Shuhei Ono is a geochemist using stable isotopes to study how microbes catalyze chemical reactions and shape the chemistry of our atmosphere and oceans. The Ono laboratory for stable isotope geochemistry studies how microbes catalyze chemical reactions and shape the chemistry of our atmosphere and oceans. 

The Ono Lab has explored the early evolution of atmospheric oxygen using stable sulfur isotope systems and developed a novel tool to pinpoint the origin of methane, significant long-lived greenhouse gas, and a key biosignature gas for space exploration. The research approach of Ono's group combines theoretical, experimental, and observational studies to answer significant questions in Earth science using stable isotopes as a versatile tool. They apply these tools to a broad range of problems in both low- and high-temperature geochemistry.

Ono holds a BSc in Geology from Waseda University, Tokyo, and a PhD in Geochemistry from Pennsylvania State University (2001). After postdoctoral research at the Geophysical Laboratory of Carnegie Institution of Washington, he joined the EAPS faculty in 2007.
