David Hawthorn, a condensed matter physicist, is an expert in experimental condensed matter studies.

Specifically, he uses X-ray scattering and spectroscopy to investigate high-temperature superconductors and other quantum materials. His recent research highlights include the invention of a new method for measuring the absorption of X-rays in materials; the development of an instrument for resonant X-ray scattering at the Canadian Light Source; and investigations of charge-density wave order in high-temperature superconductors, using resonant X-ray scattering.
