Tomás Palacios, the Clarence J. LeBel Professor of Electrical Engineering at MIT, has been appointed director of the MIT Institute for Soldier Nanotechnologies (ISN). Palacios assumed the role on Feb. 4, and will continue to serve as the director of the MIT Microsystems Technology Laboratories (MTL).
Founded in 2002, ISN is a U.S. Army-sponsored University Affiliated Research Center focused on advancing fundamental science and engineering to enable next-generation capabilities for protection, survivability, sensing, and system performance. ISN brings together researchers from across MIT to address challenges at the intersection of materials, devices, and systems. In collaboration with industry, MIT Lincoln Laboratory, the U.S. Army, and other U.S. military services, ISN works to transition promising technologies for both commercial and defense applications.
As director, Palacios will oversee ISN’s research portfolio, facilities, and strategic partnerships, working closely with the ISN leadership team, MIT administration, U.S. Army, and other research sponsors to guide the institute’s next phase of research and collaboration.
“Tomás Palacios brings exceptional energy, vision, and leadership to the Institute for Soldier Nanotechnologies,” says Ian A. Waitz, MIT’s vice president for research, who announced the appointment in a recent letter. “As director of Microsystems Technology Laboratories, he has demonstrated a rare ability to build strong research communities and partnerships across academia, industry, and government. I am confident he will guide ISN’s next phase with momentum, scientific excellence, and a deep sense of service to MIT and the nation.”
Palacios brings deep leadership experience within MIT and across national research collaborations. As director of MTL, he leads one of MIT’s flagship interdisciplinary research laboratories supporting work in micro- and nano-scale materials, devices, and systems. He is a member of the MIT.nano Leadership Council and, since 2023, has served as associate director of the multi-university SUPeRior Energy-efficient Materials and dEvices (SUPREME) Center, a Semiconductor Research Corp. JUMP 2.0 program focused on next-generation energy-efficient semiconductor technologies. Palacios is also the co-founder of several technology companies, including Vertical Semiconductor, Finwave Semiconductor, and CDimension, Inc.
“MIT’s motto, ‘mens et manus’ — ‘mind and hand’ — reminds us that fundamental research and real-world impact must go hand-in-hand,” says Palacios. “At ISN, our mission is to help protect and empower those who defend our nation. That responsibility demands urgency, creativity, and deep collaboration. I look forward to building on ISN’s strong partnership with the U.S. Army, industry, and colleagues across MIT to push the frontiers of nanotechnology and translate discovery into meaningful impact at the speed of relevance.”
Palacios is internationally recognized for his work on wide-bandgap semiconductors, nanoelectronics, and advanced electronic materials. An IEEE Fellow, his research spans fundamental device physics through system-level integration, with applications in high-power and high-frequency electronics, sensing, and energy systems. He is widely recognized for his research contributions, as well as for his leadership in education and mentoring.
Palacios succeeds John Joannopoulos, who served as ISN director from 2006 until his death in August 2025. During his nearly two decades of ISN leadership, Joannopoulos strengthened ISN’s interdisciplinary culture, devoting significant effort to fostering collaborations among ISN-funded principal investigators, building partnerships that extend across MIT and beyond to the Army research community. Joannopoulos, an extraordinary researcher and a generous mentor, was also a co-founder of companies such as WiTricity and OmniGuide, helping to translate many of ISN’s foundational scientific discoveries into commercial technologies. Raúl Radovitzky, ISN’s associate director, served as interim director during the search for a new director, providing continuity to ISN’s research programs, facilities, and partnerships.
“It is an honor to serve as director of the Institute for Soldier Nanotechnologies at such an important moment in time,” says Palacios. “ISN has built an extraordinary foundation of interdisciplinary excellence under Professor John Joannopoulos’ leadership and, more recently, Prof. Radovitzky’s. I look forward to working with the ISN community to advance breakthrough research at the intersection of materials, devices, and systems — research that not only strengthens national security, but also translates into technologies that benefit society more broadly.”
