Fatima AL ALI

PhD Student, Université du Littoral Côte d'Opale
I am a second year PhD student in atmospheric sciences between Université du Littoral Côte d'Opale and IMT Nord Europe, France. In my thesis I study the nighttime atmospheric reactivity between methylated-furan compounds and NO3 radical in two simulation chambers (CHARME and THALAMOS). As analytical and atmospheric chemist, my work is based on qualitative and quantitative characterization of the gaseous products of these reactions using different analytical methods and spectrometric and spectroscopic techniques. So, my research is focused on understanding the oxidative mechanisms of these reactions, besides measuring the rate coefficients and estimating their lifetimes. In my thesis, I also aim on understanding SOA formation from these reactions and their chemical composition. Before I started my thesis, I did my Bachelor's degree in chemistry and Masters degree in analytical chemistry at the Lebanese University and did my internship on PM2.5 source apportionment for a pollution campaign using positive matrix factorization at Université de Reims Champagne-Ardenne, France

My main research interest are atmospheric aerosols: Tiny airborne particles with huge impacts on climate and air quality – two topics that are of imminent importance for society and the environment. Aerosols are at the interface of the different spheres of the planet and the different phases in the atmosphere, and thus key to understanding biogeochemical processes. The characterization of the chemical composition of (organic) aerosol particles and organic trace gases by means of advanced mass spectrometric techniques, and the investigation of their sources, formation and transformation processes, and fate in the atmosphere in the field and laboratory, lie at the heart of my research.

I then moved for my postdoc to the Forschungszentrum Jülich, Germany, to focus on investigating the chemical degradation of biogenic and anthropogenic volatile organic compounds with targeted experiments in the atmospheric simulation chamber SAPHIR. The goal of the experiments is to gain a better understanding on how secondary pollutants such as ozone and secondary organic aerosol are formed. I remained in the Forschungszentrum Jülich and I am now a group leader focusing, among other topics, on a better understanding of the chemistry of peroxy radicals in particular in the expected future chemical regimes (low NOx).
