Professor Paul Corkum, a physics researcher at the University of Ottawa best known for his pioneering contributions to attosecond science, has been awarded the American Physical Society’s 2025 APS Medal for Exceptional Achievement in Research.

This prestigious prizeexternal link recognizes groundbreaking contributions that significantly advance our understanding of the physical universe. The citation accompanying the award highlights Corkum’s synthesis of plasma physics, strong-field spectroscopy and electron scattering concepts to create a new field of strong-field physics, which spans atomic to solid-state physics.

Pushing boundaries to capture the infinitely small

While at the Joint Attosecond Science Laboratory (JASLab), which later brought together NRC and uOttawa researchers, Corkum and his JASLab colleagues were responsible for taking a photo of an electron orbiting an atom. The technology developed for doing so uses extremely short pulses of light and a special camera to capture images of infinitely small particles.

“To give you a sense of how short the pulses are, comparing one attosecond to one second is like comparing one second to the age of the universe,” says Corkum.

Revolutionizing physics with attosecond science

Corkum’s research in laser technology began in the 1990s. This research, a sub-area of photonics, brings physicists closer to controlling the movements of electrons inside molecules. This could lead to advances in telecommunications, computing, engineering and medicine.

“His breakthroughs in attosecond science have laid the foundation for the next generation of research in this field. This prestigious recognition is a testament to an illustrious researcher whose thirst for understanding has had a significant impact on the world around us,” says University of Ottawa President and Vice-Chancellor Jacques Frémont.

“Because of their precision, lasers are used in a variety of applications in different fields,” says Corkum. “We’ve now got a laser technique to start doing laser physics of cells – we might do laser medicine on cells. I think laser diagnostics is a very exciting area to examine.”

Key player in the Advanced Research Complex

Corkum, along with geoscientist Ian Clark, gave a healthy jump-start to the development of the University of Ottawa’s Advanced Research Complex (ARC) by applying for and receiving more than $26 million in funding from the Canada Foundation for Innovation and the Ontario Research Fund.

Together, their grants provided the vital seed funding needed to build the research hub.

Corkum is also co-director of the Max Planck-University of Ottawa Centre for Extreme and Quantum Photonics. The centre links two of the worlds foremost research teams in the field of photonics and is only the third Max Planck Centre in North America.
