Research Interest
Dr Hallé is a professor and an expert well recognized for the evaluation of the potential risks associated with the inhalation of nanoparticles. One of the basic elements for the risk assessment evaluation in a work environment consists of an adequate characterization of the degree of exposure. To achieve this objective, his research activities focus on the development and validation of numerical models able to represent the dominant particles transport and agglomeration mechanisms of airborne nanoparticles. Another aspect on Dr Hallé’s current research activities consists to study the heat transfer modes in dynamic fenestration systems such as electrochromic (EC) windows in order to optimize their thermal performances. EC windows makes it possible to improve both the building energy performance and the visual environment of the occupants. EC windows act as active components which can modulate the glazing optical properties in order to attain energy saving and a reduction of glare phenomena.
He is a member of the Quebecer Community in Nanoxicology, an initiative of The Research Network in Health and Security in the Workplace of Quebec supported by the FRSQ (Fonds de Recherche en Santé du Québec.
