Nuno Loureiro MIT professor and nuclear scientist shot dead at Brookline, Massachusetts home as investigators continue to seek suspect. No known motive.
Massachusetts authorities have intensified their search for a suspect following the fatal shooting of a MIT professor at their Brookline, Mass. home Monday night.
Nuno F.F Loureiro a 47 year old physicist and fusion scientist and professor at Massachusetts Institute of Technology was shot at his apartment in Brookline, Massachusetts, Monday night. The father of three died at a local hospital on Tuesday, the Norfolk District Attorney’s Office said in a statement.
The prosecutor’s office said the homicide investigation was ‘active and ongoing,’ with the office stating to date no suspects were in custody.
MIT Professor shooting death raises questions
The shooting took place on the first-floor apartment where Loureiro lived in the three-story building, which he bought with his wife in 2018 for $1.4 million, property records show.
The investigation into the MIT professor’s killing comes as Brown University, another prestigious institution just 50 miles (80 kilometers) away in Providence, Rhode Island, is reeling from an unsolved shooting that killed two students and wounded nine others Saturday. Investigators provided no indication Tuesday that they were any closer to zeroing in on the gunman’s identity.
The FBI on Tuesday said it knew of no connection between the crimes.
Loureiro was considered one of the world’s leading researchers in energy and nuclear physics and has served in key roles at research centers related to the development of future technologies.
Loureiro, joined MIT in 2016, before going on to head up MIT’s Plasma Science and Fusion Center, where he worked to advance clean energy technology and other research. The center, one of the school’s largest labs, had more than 250 people working across seven buildings when he took the helm last year according to AP.
What was nuclear scientist bringing to the fold?
Loureiro, who was married, grew up in Viseu in central Portugal and studied in Lisbon before earning a doctorate in London. He was a researcher at an institute for nuclear fusion in Lisbon before joining MIT, the university said.
The president of MIT, Sally Kornbluth, said in a statement that the killing was a ‘shocking loss.’
Loureiro had said he hoped his work would shape the future.
‘It’s not hyperbole to say MIT is where you go to find solutions to humanity’s biggest problems,’ Loureiro said when he was named to lead the plasma science lab last year. ‘Fusion energy will change the course of human history.’
MIT plasma scientist Nuno F. G. Loureiro was shot inside his home late Monday in a killing authorities are now investigating as a homicide.

Incentive to take out ground breaking scientist?
Posted J Stewart on X: ‘Nuno Loureiro, MIT’s leading nuclear fusion scientist pushing clean energy breakthroughs, was murdered at his home yesterday. Shot dead at 47, his plasma physics research could’ve changed the world—now silenced. Not the first MIT fusion scientist to meet a tragic end.
‘In 1989, Eugene Mallove exposed a cold fusion cover-up by the DoE and MIT after excess heat was reproduced dozens of times. In 2004, he was brutally murdered in his home. Coincidence?’
Authorities had yet to say why the researcher and professor was targeted and whether they had any suspicions about who could’ve been involved, including a possible state actor.
