On December 15, 2025, Nuno F. G. Loureiro, a Prominent Portuguese physicist and director of MIT’s Plasma Science and Fusion Center, was fatally shot at his home in Brookline, Massachusetts. He was 47 years old.
Police responded to reports of gunfire between 8:30 and 9 p.m. at his apartment building on Gibbs Street, where Loureiro was found with multiple wounds in the foyer. Despite being rushed to a Boston hospital, he succumbed to his injuries early the next morning. Massachusetts authorities have launched an active homicide investigation, though no suspects are currently in custody.
Born in 1977 in Viseu, Portugal, Loureiro came from a Sephardic Jewish family and pursued an exceptional academic path. He earned his physics degree from Instituto Superior Técnico in Lisbon in 2000, followed by a PhD from Imperial College London in 2005. His postdoctoral work at the Princeton Plasma Physics Laboratory and subsequent research at the Institute for Plasmas and Nuclear Fusion in Lisbon established him as a rising figure in plasma physics.
In 2016, Loureiro joined MIT as a professor of nuclear science and engineering and physics. He advanced to deputy director and, in 2024, became director of the Plasma Science and Fusion Center. His research focused on plasma turbulence and magnetic reconnection, using theoretical and computational methods to address challenges in fusion energy. In January 2025, he was honored with the Presidential Early Career Award for Scientists and Engineers by President Joe Biden, recognizing his transformative contributions to the field.
Beyond his professional achievements, Loureiro was a devoted husband and father. He lived with his family in Brookline, where neighbors described a warm household with children attending local schools. He balanced his demanding research with family life, maintaining privacy while fostering a supportive home environment.
The Brookline and MIT communities have been shaken by his death. Authorities have increased patrols in the neighborhood, and MIT has extended support services to students and colleagues affected by the tragedy. Investigators have ruled out links to other recent incidents, emphasizing the ongoing nature of the probe in Norfolk County.
Nuno F. G. Loureiro is remembered for his pioneering work in plasma physics, his mentorship at MIT, and his deep commitment to family. His legacy endures through groundbreaking research, the students and colleagues he inspired, and the compassionate example he set in both professional and personal spheres.
