Olivier Duclaux received the Ph.D. degree in kinetics and catalysis from the University of Lyons, Lyon, France, in 1997, for his work on VOC's destruction. He is currently a Senior Researcher with the Air Quality Laboratory, Oil & Gas Company TOTAL, Solaize, France. He participates in the elaboration of several CEN standards for fugitive/diffuse emission quantification by remote sensing and reverse modeling approach. He is involved as Expert in the Conservative Clean Air & Water for Europe consortium for the quantification of emission from the refining activity. With combined industrial and academic experience, his research includes numerical modeling of atmospheric processes, pollutant analysis, and reduction technologies. His current research focuses on the quantification of pollutants by combining measurement from various technologies (optical; punctual, monitoring network) to a reverse modeling approach.
