He was a friend to many at the IPP
The Max Planck Institute for Plasma Physics (IPP) mourns the loss of Portuguese plasma physicist Professor Nuno Loureiro from MIT, who died on 16 December as a result of a violent crime.
The news of Professor Nuno Loureiro's death has been received with great sadness and dismay at both IPP locations in Garching and Greifswald. The plasma physicist had been Director of the Plasma Science and Fusion Centre (PSFC) at the Massachusetts Institute of Technology (MIT) since May 2024. He died in the early hours of 16 December 2025 from gunshot wounds sustained a few hours earlier.
Prof. Loureiro was born in Portugal in 1977, studied physics in Lisbon and eventually earned his doctorate in plasma physics at Imperial College London. He went on to work at the Princeton Plasma Physics Laboratory, the UKAEA Culham Centre for Fusion Energy, and the Instituto de Plasmas e Fusão Nuclear in Lisbon before moving to MIT as a faculty member in 2016.
His scientific achievements were profound. Already as a PhD student, he achieved a breakthrough in the study of magnetic reconnection by delivering a key insight to an old puzzle: why are magnetic field lines able to change topology (“reconnect”) so rapidly in a low-resistivity plasma? Why are solar flares and tokamak sawtooth crashes so sudden? Loureiro showed that the half-century-old textbook mechanism for magnetic reconnection is unstable, and the resulting instability greatly accelerates the reconnection process. He went on to show how this process affects electromagnetic turbulence in astrophysical and fusion plasmas.
Per Helander, Director at IPP in Greifswald says: "Thanks to his warm personality and intellectual brilliance, Prof. Loureiro formed a wide network of scientific collaborations, which included many IPP scientists and often turned into deep friendships. Always friendly, considerate and wildly humorous, he won many hearts and will be sorely missed by all who had the privilege to know him. His family, friends and colleagues are in our thoughts."
