Prof. Patrick J Rochette is a full professor and the dean of ophthalmology research department at Laval University. He is also a senior researcher at the Research Centre of the CHU of Quebec, Canada. He is specialised in photobiology and, more precisely, on the molecular consequences of exposure to ultraviolet and blue light. Prof. Rochette’s laboratory is interested in two fields of study: ocular and cutaneous photobiology. At the cutaneous level, skin cells are used as a model to study the mechanisms of protection against the genotoxicity of UV. At the ocular level, his research aims to understand the molecular mechanisms involved in UV/blue light and atmospheric pollution on ocular health.
