He is a member of the International Fingerprint Research Group (IFRG), to which are invited only the most active and creative researchers of the domain.

Fingerprint
A fingerprint in its narrow sense is an impression left by the friction ridges of a human finger. In a wider use of the term, fingerprints are the traces of an impression from the friction ridges of any part of a human hand. A print from the foot can also leave an impression of friction ridges...

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of photons. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation...

Work
In 1977 start a collaboration between Brian Dalrymple and the Xerox Research Centre to develop a new method of using an argon ion laser to detect fingerprints by inherent fluorescence. The OPP became the first police agency in the world to use this new technology on a regular basis. The laser technique is a non-destructive method that allow the use of other fingerprint detection following the laser observation. This use of the laserLaser
