Antony Lomax has played a defining role in the evolution of modern proton therapy. At the Paul Scherrer Institute (PSI) in Switzerland, where he has worked for more than three decades, he was part of the pioneering team that helped transform proton therapy from an experimental concept into an established clinical standard. He was instrumental in the development of pencil-beam scanning and intensity-modulated proton therapy (IMPT), including the world’s first clinical IMPT treatment at PSI in 1999.

With a long track record of scientific leadership, innovation, and collaboration across the international proton therapy community, Antony Lomax brings deep expertise to RaySearch.

“RaySearch combines deep scientific capabilities with a clear ambition to shape the future of radiation oncology. I look forward to contributing my experience in proton therapy as RaySearch continues to advance particle treatments and get the possibility to explore new treatment modalities,” says Antony Lomax.

“Antony Lomax is widely regarded as one of the pioneers in proton therapy, and his experience and reputation in the field will be tremendously valuable to us. As particle therapy becomes increasingly important, his perspective will help further strengthen our position and deepen our relevance for customers, partners, investors, and the broader oncology community,” comments Johan Löf, founder and CEO of RaySearch.

Antony Lomax will assume the role of Clinical Ambassador Particle Therapy at RaySearch on August 12, 2026, as part of the newly established Corporate Development and Strategy department.
