Identification and quantification of primary and secondary molecular markers in atmospheric aerosol using mass spectrometry techniques (GC/MS, HPLC/APCI-MS2 , HPLC/ESI-MS2).
Source apportionment of organic aerosol in ambient atmospheres using molecular markers, 14C measurements and AMS data combined with statistical models (e.g. Chemical Mass Balance, CMB).
Chemical characterization of main emission sources of hydrocarbons and organic aerosol (e.g. cooking processes, combustion engines, wood burning ...), determination of the related emission factors and quantification of their secondary organic aerosol potential by means of smog chamber experiments.
Characterization of gas phase and in-cloud aqueous phase aging processes and their impact on the molecular marker profiles, on the formation of high molecular weight compounds (i.e. oligomers) and on the organic aerosol functional groups and oxidation state
2007 – 2010 MENRT research fellowship from the French ministry of research
2005 Excellence Scholarship from the University of Saint Joseph as the top 1% students of the faculty of sciences
2005 “Distinction Prize” from the University of Saint Joseph as the best student in the class of 2005.
