Jeffrey R. Long

Jeffrey Robert Long is an American chemist who is currently the C. Judson King Distinguished Professor at the University of California, Berkeley, and the Director of the Baker Hughes Institute for Decarbonization Materials. Broadly, Long’s research group at Berkeley is centered on controlling chemical structure and function through molecular design. Long has contributed significant advances in the areas of chemistry, chemical engineering, materials science, and physics. More specifically, he is known for the synthesis of novel adsorbent materials for capturing and storing small molecules such as CO₂, O₂, and H₂—in particular those relevant to decarbonization—as well as his seminal work in the area of molecular quantum magnetism. In 2015, with two graduate students from his research group, Long founded the company Mosaic Materials, which set out to commercialize a new class of materials for carbon capture. In 2022, Mosaic was acquired by the global energy technology company Baker Hughes, who is now scaling the technology for deployment in capturing CO₂ directly from the atmosphere. Long is a member of the National Academy of Sciences and the American Academy of Arts and Sciences. He has published over 400 scientific papers during his independent career, with over 100,000 citations and an h-index of 145. In addition, he has filed over 20 patents stemming from technology developed within his laboratory.
