About Patrick
I am responsible for the experimental biology aspects of the standard toxicological assessment of Reduced-Risk Products (RRPs). I lead the in vitro and in vivo laboratories performing Good Laboratory Practice studies to characterize the hazard associated with the aerosols from RRPs in comparison to conventional cigarette smoke.
