Professor Ola Hermanson, who served as a distinguished member of the neuroscience community at Karolinska Institutet, passed away on 2 October 2025 at the age of 60. His career was marked by scientific excellence, visionary leadership, and a deep commitment to the advancement of neuroscience both in Sweden and internationally.

Ola Hermanson began his academic journey at Lund University where he studied medicine, followed by doctoral studies in medical cell biology at Linköping University. His postdoctoral tenure at the University of California, San Diego, was transformative, not only for his own research trajectory but also for the laboratories and colleagues with whom he collaborated. Ola Hermanson was recognised for his intellectual rigour, creativity, and ability to foster a collaborative and collegial environment.

Innovative researcher and dedicated mentor

Upon his return to Sweden, Ola Hermanson established his research group at Karolinska Institutet, where he made pioneering contributions to the understanding of epigenetic mechanisms in brain development and disease. He was among the first in Sweden to employ bioprinting technology for the cultivation of neural cells, and his work in neuroepigenomics and stem cell bioengineering was widely regarded as ahead of its time. Ola Hermanson’s research was characterised by originality, methodological innovation, and a commitment to addressing complex scientific questions.

Ola Hermanson was a source of innovative ideas and a catalyst for collaborative projects, often inspiring colleagues to pursue bold new directions. His impact extended far beyond his scientific achievements. He was a mentor who cared deeply for his students and colleagues, always ready with advice, encouragement, and a touch of humour. Many recall his open-door policy, his encyclopaedic knowledge, and his unique ability to make everyone feel valued. His generosity was evident in the countless ways he supported those around him, from sharing grant-writing tips to celebrating the successes of his mentees as if they were his own.

Fostering global collaboration and scientific exchange

Ola Hermanson’s contribution to Karolinska Institutet and the broader academic community was exemplary. He played a central role in fostering international collaborations, notably with Canadian universities, and was instrumental in the establishment of the Mats Sundin Fellowship Foundation, which supports the international mobility of young researchers. As scientific director of the Ming Wai Lau Centre for Reparative Medicine in Hong Kong, Professor Hermanson further extended his impact, facilitating cross-continental scientific exchange and nurturing the next generation of neuroscientists.

A life enriched by music and culture

Ola Hermanson’s talents were not confined to the laboratory. He was a passionate musician, a founder of the indie label Ceilidh Productions, and a singer and guitarist in the surf rock band Sonic Surf City, which achieved cult status in Japan. His love of music, culture, and life enriched the community at KI and beyond.

Above all, Ola Hermanson will be remembered for his kindness, humour, and the joy he brought to those around him. He had a rare gift for making people feel seen and heard, and his legacy lives on in the many lives he touched.
The neuroscience community mourns the loss of a remarkable scientist, mentor, and friend.

The Department of Neuroscience held a gathering in memory of Ola Hermanson on Friday 24 October 2025, in the Faculty Club in Biomedicum.
