MIT called Loureiro, director of the university’s Plasma Science and Fusion Centre, a “lauded theoretical physicist and fusion scientist”.
He joined MIT’s faculty in 2016 and his research “addressed complex problems lurking at the centre of fusion vacuum chambers and at the edges of the universe”, the university said.
US ambassador to Portugal John Arrigo wrote on X that he extends his “deepest condolences to the family, friends, and colleagues of Nuno Loureiro”.
“We honour his life, his leadership in science, and his enduring contributions,” he added.
MIT professor Dennis Whyte, a previous director of the centre, called Loureiro’s loss “immeasurable to our community...and around the entire fusion and plasma research world”.
Police in Rhode Island, who are investigating a weekend mass shooting at the campus of Brown University, said that the two incidents were unrelated.
