Long is the Thomas C. Foley Professor of Energy and the Environment at Harvard University and Director of the Harvard Materials Initiative. His research combines molecular design, inorganic chemistry, and materials science to create new functional materials that address some of society's most pressing challenges in energy, sustainability, and resource security. Long's laboratory is internationally recognized for developing porous materials that selectively capture, separate, and store small molecules relevant to decarbonization, including carbon dioxide, methane, hydrogen, oxygen, and water. His group has pioneered new classes of metal–organic frameworks and related materials whose chemical properties can be precisely tuned at the molecular level, enabling breakthroughs in carbon capture, gas separations, and chemical sensing. More recently, his research has expanded to the design of porous materials for recovering critical minerals from waste streams and low-grade ores, helping to establish new approaches to the circular economy and the secure supply of critical materials. In parallel, his laboratory has made fundamental contributions to the chemistry and physics of magnetic molecules and materials, advancing the understanding of strongly correlated electronic systems and molecular magnetism. Long received bachelor's degrees in Chemistry and Mathematics from Cornell University in 1991, where he was awarded the Mandelkern Prize. He earned his Ph.D. in Chemistry from Harvard University in 1995 under the guidance of Professor Richard H. Holm, studying inorganic solid-state frameworks and developing synthetic approaches to systematically reduce their dimensionality from extended solids to molecular clusters. Following postdoctoral research with Professor Paul Alivisatos at the University of California, Berkeley, he joined the Berkeley faculty in 1997. Over nearly three decades at Berkeley, Long built one of the world's leading research programs in inorganic and materials chemistry. He served as Professor of Chemistry, Chemical and Biomolecular Engineering, and Materials Science and Engineering, as well as Faculty Senior Scientist in the Materials Sciences Division at Lawrence Berkeley National Laboratory. In 2022, he was named the C. Judson King Distinguished Professor. In 2027, he returned to Harvard as the inaugural Thomas C. Foley Professor of Energy and the Environment and the founding Director of the Harvard Materials Initiative. Long has translated discoveries from his laboratory into commercial technologies through two startup companies. He co-founded Mosaic Materials in 2014 to develop advanced adsorbent materials for carbon capture from industrial gas streams, natural gas, biogas, and air. Following its acquisition by Baker Hughes in 2022, the company's technologies have advanced toward large-scale industrial deployment, including multi-ton production of metal–organic framework adsorbents. In 2022, he co-founded ChemFinity Technologies, which is developing new porous materials and processes for the efficient recovery of critical minerals from mining and industrial waste streams. Long has authored more than 400 scientific publications, which have been cited over 100,000 times, and is an inventor on more than 20 patents. He is a member of the American Philosophical Society, the National Academy of Sciences, and the American Academy of Arts and Sciences. Jeffrey R.
