Tragic Shooting of MIT Professor Nuno Loureiro in Brookline

On Monday evening, December 15, 2025, Nuno F.G. Loureiro, a 47-year-old professor at the Massachusetts Institute of Technology (MIT) and director of its Plasma Science and Fusion Center, was fatally shot at his home on Gibbs Street in Brookline, Massachusetts. He was transported to Beth Israel Deaconess Medical Center in Boston, where he succumbed to multiple gunshot wounds early Tuesday morning, December 16, 2025.

Brookline police responded to reports of gunshots around 8:30–9:00 p.m. and found Loureiro in the foyer of his apartment building with severe injuries. Neighbors reported hearing multiple loud bangs, and one described seeing him on the floor while calling 911 alongside his wife and others.

The Norfolk County District Attorney’s Office, along with Massachusetts State Police, Brookline Police, and MIT Police, is investigating the incident as a homicide. No suspects have been identified or taken into custody, and authorities have released limited details, describing it as an “active and ongoing” investigation. Increased police presence has been noted in the neighborhood.

Loureiro, originally from Portugal, was a prominent physicist specializing in plasma dynamics and nuclear fusion. He joined MIT in 2016, became deputy director of the Plasma Science and Fusion Center in 2022, and was appointed director in 2024. Colleagues described him as a brilliant scientist, mentor, and leader. MIT President Sally Kornbluth called his death a “shocking loss,” and the university is providing support to his family, students, and community.

Tributes poured in from around the world, including from the U.S. Ambassador to Portugal and Portuguese officials. Neighbors organized a candlelight vigil on Tuesday evening in his memory.

Some online speculation and reports from pro-Israel media outlets (such as Israel National News, The Yeshiva World, and JFeed) have claimed Loureiro was Jewish and outspokenly pro-Israel, suggesting a possible targeted motive amid rising concerns over antisemitism and threats to Jewish or pro-Israel academics. However, mainstream sources—including The New York Times, Boston Globe, CNN, ABC News, NBC, CBS, BBC, AP, and PBS—do not mention his religion or political views, focusing solely on the facts of the shooting and his professional achievements. Authorities have not indicated any motive, including whether it could be a hate crime.

This remains a developing story with no arrests or confirmed motive as of December 17, 2025. The community in Brookline and at MIT is mourning the loss of a respected scholar.
