I hold a Ph.D. in ore geology and an MS in organic geochemistry from the University of Tunis. I currently work at the Earth and Planetary Division, Physical Sciences, City University of New York - Kingsborough College. My area of focus in research encompasses three primary themes: mineral resources, organic geochemistry, and low-temperature geochemistry, with a particular emphasis on regions in the USA and North Africa. In the first theme, my aim is to understand the origin of mineral resources by employing various analytical techniques such as stable and radioactive isotopes, microthermometry, and Rare Earth Elements analysis. The second theme is centered on identifying potential source rocks for hydrocarbons, primarily through the utilization of Rock-Eval analysis. Lastly, the objective of the third theme is to investigate the presence and distribution of trace elements, such as arsenic and boron, which can contaminate groundwater.
