Paula Hammond '84, PhD '93, an Institute Professor and MIT's executive vice provost, has been named dean of MIT's School of Engineering, effective Jan. 16. She will succeed Anantha Chandrakasan, the Vannevar Bush Professor of Electrical Engineering and Computer Science, who was appointed MIT's provost in July. Hammond, who was head of the Department of Chemical Engineering from 2015 to 2023, has also served as MIT's vice provost for faculty. She will be the first woman to hold the role of dean of MIT's School of Engineering. 'From the rigor and creativity of her scientific work to her outstanding record of service to the Institute, Paula Hammond represents the very best of MIT,' says MIT President Sally Kornbluth. 'Wise, thoughtful, down-to-earth, deeply curious, and steeped in MIT's culture and values, Paula will be a highly effective leader for the School of Engineering. I'm delighted she accepted this new challenge.' Hammond, who is also a member of MIT's Koch Institute for Integrative Cancer Research, has earned many accolades for her work developing polymers and nanomaterials that can be used for applications including drug delivery, regenerative medicine, noninvasive imaging, and battery technology....

Each year, faculty and researchers across the MIT School of Engineering are recognized with prestigious awards for their contributions to research, technology, society, and education. To celebrate these achievements, the school periodically highlights select honors received by members of its departments, institutes, labs, and centers. The following individuals were recognized in summer 2025: Iwnetim Abate, the Chipman Career Development Professor and assistant professor in the Department of Materials Science and Engineering, was honored as one of MIT Technology Review's 2025 Innovators Under 35. He was recognized for his research on sodium-ion batteries and ammonia production. Daniel G. Anderson, the Joseph R. Mares (1924) Professor in the Department of Chemical Engineering and the Institute of Medical Engineering and Science (IMES), received the 2025 AIChE James E. Bailey Award. The award honors outstanding contributions in biological engineering and commemorates the pioneering work of James Bailey....

China dominates the global supply of lithium. The country processes about 65 percent of the battery material and has begun on-again, off-again export restrictions of lithium-based products critical to the economy. Fortunately, the U.S. has significant lithium reserves, most notably in the form of massive underground brines across south Arkansas and east Texas. But recovering that lithium through conventional techniques would be an energy-intensive and environmentally damaging proposition ' if it were profitable at all. Now, the startup Lithios, founded by Mo Alkhadra PhD '22 and Martin Z. Bazant, the Chevron Chair Professor of Chemical Engineering, is commercializing a new process of lithium recovery it calls Advanced Lithium Extraction. The company uses electricity to drive a reaction with electrode materials that capture lithium from salty brine water, leaving behind other impurities. Lithios says its process is more selective and efficient than other direct lithium-extraction techniques being developed. It also represents a far cleaner and less energy-intensive alternative to mining and the solar evaporative ponds that are used to extract lithium from underground brines in the high deserts of South America....

MIT researchers have developed a lightweight polymer film that is nearly impenetrable to gas molecules, raising the possibility that it could be used as a protective coating to prevent solar cells and other infrastructure from corrosion, and to slow the aging of packaged food and medicines. The polymer, which can be applied as a film mere nanometers thick, completely repels nitrogen and other gases, as far as can be detected by laboratory equipment, the researchers found. That degree of impermeability has never been seen before in any polymer, and rivals the impermeability of molecularly-thin crystalline materials such as graphene. 'Our polymer is quite unusual. It's obviously produced from a solution-phase polymerization reaction, but the product behaves like graphene, which is gas-impermeable because it's a perfect crystal. However, when you examine this material, one would never confuse it with a perfect crystal,' says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT....
