Portuguese neuroscientist joins Nobel Committee in historic first for brain research

A Portuguese neuroscientist has been recognised for his groundbreaking research in brain science. Gonçalo Castelo-Branco, a professor at Sweden's Karolinska Institute, was reportedly appointed to the Nobel Committee for Physiology or Medicine. The news has drawn praise from Portugal's leadership, though official confirmation remains pending as of March 2026.

Castelo-Branco has gained international attention for his work on oligodendrocytes and myelin formation. His studies, published in Nature (2018) and Cell (2021), used single-cell RNA sequencing to explore multiple sclerosis and neural plasticity. These discoveries have advanced understanding of how the brain repairs itself.

The Nobel Committee for Physiology or Medicine typically includes five members and the Secretary-General of the Nobel Assembly. If confirmed, Castelo-Branco would join a group responsible for selecting laureates in one of the most prestigious scientific awards. The prize itself consists of a diploma, a gold medal, and 11 million Swedish kronor (around one million euros). Portugal's head of state and António José Seguro have both congratulated Castelo-Branco on his reported appointment. The recognition highlights the growing influence of Portuguese researchers in global science. The Nobel Prizes, established in 1895 by Alfred Nobel, have been awarded annually since 1901, with the Physiology or Medicine prize decided at the Karolinska Institute.

The appointment, if finalised, would mark a significant achievement for Portuguese science. Castelo-Branco's research has already contributed to key breakthroughs in neuroscience. Official confirmation from the Nobel Assembly is still awaited as of early 2026.
