Salma Bejaoui


Salma Bejaoui is currently a NASA Postdoctoral fellow at NASA Ames Research Center. The fellowship is managed by (USRA) and if you would like to know about that program please visit their web site for more information.

Salma grew up in Tunisia, where she obtained her energy engineer degree and master degree. She was initiated on research on a combustion laboratory (Physicochimie de processus de combustion et de l'atmosphère, in French, PC2A) where she received her PhD degree from the University of Lille 1 (France). Her research focused on applying laser-based diagnostics such as Laser induced incandescence and Laser induced fluorescence to study the formation process of polycyclic aromatic hydrocarbon (PAHs) and soot in flame conditions.

Salma started a 1-year post doc in the laboratory TEMPO in Valenciennes (France) and ENERBIOM factory for the thermal characterisation and analysis of the emission of pollutants in a wood boiler. In 2014, she worked for the laboratory "Ecole Centrale de Paris (France)". The objective of the post-doctoral fellowship is to study the influence of acoustic perturbations on the dynamic and thermal structure of a premixed swirling flame using laser based diagnostic.

Salma is currently working in the Astrophysics & Astrochemistry Laboratory with Farid Salama to study the absorption and emission spectroscopy of cold and isolated PAHs on the Cosmic Simulation Chamber (COSmiC). It uses a pulsed discharge nozzle to ionize PAH-seeded gases and generate atomic and molecular ions, neutrals and radicals which are then expanded in a free-jet expansion at temperature and pressure conditions close to interstellar medium. Cavity ring down spectroscopy is used to measure the absorption of neutral and ionized PAHs. Laser induced fluorescence is applied to measure the emission of cold PAHs.

Salma's major publications can be found on the Astrochemistry Laboratory's Publications Pages.
