A professor at the Massachusetts Institute of Technology was shot and killed at his home in Boston on Monday night. Law enforcement is still investigating the incident, while nothing suggests a connection to the shooting that occurred at Brown University this weekend.

Nuno F.G. Loureiro was shot at his home in Boston

Law enforcement responded to a call for gunshots at around 8:30 p.m. on Monday, according to the BBC. A neighbor reportedly heard “three loud bangs” and thought someone was kicking in a door in the apartment building.

Loureiro was taken to the hospital with multiple gunshot wounds. He was pronounced dead on Tuesday morning, according to the Norfolk District Attorney’s office.

The shooting remains “an active and ongoing homicide investigation,” and no suspect was brought into custody. A senior law enforcement official said there was nothing to suggest the shooting is connected to the mass shooting that happened at Brown University over the weekend, according to ABC News.

Who was Nuno F.G. Loureiro?

Loureiro was a professor in MIT’s departments of Nuclear Science & Engineering and Physics, as well as the Director of MIT’s Plasma Science and Fusion Center. He joined MIT in 2016 and “quickly became known as an imaginative scholar, gifted administrator and enthusiastic mentor,” MIT President Sally Kornbluth said in a statement.

“In the face of this shocking loss, our hearts go out to his wife and their family and to his many devoted students, friends and colleagues,” she added. “This shocking loss for our community comes in a period of disturbing violence in many other places. It’s entirely natural to feel the need for comfort and support. … In time, the many communities Nuno belonged to will create opportunities to mourn his loss and celebrate his life.”

Loureiro was 47 years old and a native of Portugal. He majored in Physics at Instituto Superior Técnico in Lisbon in 2000 and obtained a PhD in physics at Imperial College London in 2005.

U.S. Ambassador to Portugal John J. Arrigo highlighted his contributions to science in a statement.

“I extend my deepest condolences to the family, friends, and colleagues of Nuno Loureiro, who led MIT’s Plasma Science and Fusion Center,” he wrote. “We honor his life, his leadership in science, and his enduring contributions.”
