Dr.Ian Watson

Dr.Ian Watson

University of Glasgow


Ian Watson’s first degree was in applied physics, followed by a PhD from the engineering Faculty at the University of Glasgow in “Optimizing the gaseous dischargeand optical coupling of a pulsed CO2 laser” which was specifically designed for material processing of reflective and refractory materials. In the early 1990s hebegan to research the effects of high power laser beams on microorganisms and laser sterilization and inactivation. He has published on the direct effect of a range of lasers and their efficacy on treating different substrates, including solids, liquids and air and a range of microorganisms from E. coli to B. globigii, ananthrax simulant. As well as building lasers and laser scanning inactivation systems he has developed combined systems for decontamination and inactivationapplications. These systems comprised: lasers, UV, pulsed flash lamp systems, microwave and chemical treatments. Laser and plasma systems have been specifically designed, fabricated and successfully tested for treating air.

Research Interest

Dr. Ian Watson is interested in how new decontamination systems and processes can lead to a safer environment and reduce the threat of food contamination and poisoning; and how the treatments can improve shelf life and food quality. As a part of this process, real time detection of microorganisms plays a role in process optimisation.
