Matthew Eisaman

Matthew Eisaman is an associate professor at Yale University in the Department of Earth & Planetary Sciences and the Yale Center for Natural Carbon Capture (YCNCC). Prior to joining Yale in 2023, he served as an associate professor at Stony Brook University with a guest appointment at Brookhaven National Lab. In 2021, Eisaman co-founded Ebb Carbon, a startup based in San Carlos, CA, that is commercializing ocean-based carbon dioxide removal (ocean CDR) and ocean acidification reversal using electrochemical ocean alkalinity enhancement. He currently advises Ebb Carbon as chief scientist. Eisaman served as a technical advisor to X, formerly known as Google[X], from 2014 to 2021, and in 2016 he led Project Foghorn at X, which aimed to create carbon-neutral liquid fuel from seawater.

Prior to Stony Brook, Eisaman was a physicist at Brookhaven National Lab from 2011 to 2014, an applied physicist in the Cleantech Innovation Program at Xerox PARC in Palo Alto, CA from 2008 to 2011, and an NRC Postdoc at NIST from 2006 to 2008. Eisaman received his PhD in Physics from Harvard and AB in Physics from Princeton in 2006 and 2000, respectively. His research has covered a broad range of clean-energy technologies, including photovoltaics and CO₂ removal.

Eisaman’s current research is focused on ocean CDR, including the optimization and commercialization of electrochemical ocean CDR; its effects on marine ecosystems; establishing and improving methods for measurement, reporting, and verification (MRV); and the potential for colocation and co-benefits of electrochemical ocean CDR with other carbon removal approaches.
