BROOKLINE, Mass. — Nuno F.G. Loureiro, a 47-year-old physicist and director of the Plasma Science and Fusion Center at the Massachusetts Institute of Technology (MIT), was fatally shot on Monday evening at his home. He was pronounced dead at a local hospital on Tuesday, prompting an ongoing homicide investigation by local authorities.

Loureiro had joined MIT in 2016 and was appointed to lead one of the university's largest laboratories last year, where he promoted research into clean energy technologies. His contributions to science earned him respect not only among peers but also among students, with many expressing their sorrow at the loss.

As of Tuesday afternoon, no suspects had been arrested in connection with the shooting, as investigators work to uncover leads. MIT President Sally Kornbluth expressed her grief over the incident, referring to Loureiro’s death as a “shocking loss.”

Witnesses reported hearing loud noises from Loureiro's neighborhood around the time of the shooting, causing alarm among local residents. One Boston University student noted, 'I assumed they were gunshots. It's difficult to grasp how this keeps happening.'

Several of Loureiro’s students visited his home to pay their respects on Tuesday, while condolences also came from U.S. officials, including the ambassador to Portugal, highlighting Loureiro's significant contributions to the scientific community.

'Fusion energy will change the course of human history,' Loureiro remarked upon his directorship, outlining his belief in the potential of research to resolve major global issues.
