Portuguese researcher Gonçalo Castelo-Branco has been elected to the prestigious Nobel Committee at the Karolinska Institute, marking a significant milestone for Portuguese science and his research into neuroinflammatory diseases.

Nobel Committee Appointment

Gonçalo Castelo-Branco was elected to the Nobel Committee for Physiology or Medicine on March 14, 2026.

Academic Background

A Professor of Glial Cell Biology at the Karolinska Institute, his work focuses on molecular mechanisms in multiple sclerosis.

National Recognition

The President of Portugal issued an official statement congratulating the scientist on the international prestige of the appointment.

Portuguese scientist Gonçalo Castelo-Branco was elected to the Nobel Committee for Physiology or Medicine on March 14, 2026. Castelo-Branco is a professor of Glial Cell Biology at the Karolinska Institute in Stockholm, Sweden. He had previously been a member of the Nobel Assembly at the Karolinska Institute, and his election to the Committee represents a further step in his involvement with the prize institution. The election was reported by multiple Portuguese outlets on March 14, 2026.

Castelo-Branco expressed satisfaction with the appointment. „"Muito contente" com o reconhecimento do seu trabalho e da sua carreira.” (Very happy with the recognition of my work and my career.) — Gonçalo Castelo-Branco via Observador His research focuses on the molecular mechanisms that regulate cells of the oligodendrocyte lineage in neuroinflammatory diseases, including multiple sclerosis. The Karolinska Institute, where Castelo-Branco is based, is the university that annually awards the Nobel Prize in Physiology or Medicine. His work in glial cell biology places him at the intersection of basic neuroscience and clinical disease research.

The President of Portugal congratulated Castelo-Branco on his election to the Nobel Committee, according to RTP. The presidential acknowledgment was reported on March 14, 2026, the same day the news of the election became public. No further details of the congratulatory message were confirmed in the available source articles.

The Nobel Prize in Physiology or Medicine has been awarded annually since the prizes were established by Alfred Nobel's 1895 will. The Karolinska Institute in Stockholm is the sole institution responsible for selecting the laureate each year. The Nobel Assembly at the Karolinska Institute elects the Nobel Committee from among its members, making election to the Committee a significant institutional distinction. Multiple sclerosis, one of the diseases central to Castelo-Branco's research, is a chronic neuroinflammatory condition in which the immune system attacks the myelin sheath of nerve cells in the central nervous system.
