Currently I am director of the LABTHOP research laboratory, and dean of the faculty of exact sciences at the University of El Oued.

In my research activities, I have mainly addressed the following themes:
– Operator theory and some properties of certain classes.
– Spectral analysis of operators and its applications.
– Operator approximations and their applications.
Also, during these years, I was able to prepare and support a European thesis at the University Claude Bernard Lyon 1, under the supervision of Mr. Gilles Cassier, CNRS-UMR 5208, entitled: Solving two types of operational equations and interactions .
I defended this thesis in front of a jury composed of leading specialists in the field, my thesis includes several results (novelty side: project of 04 papers will be published).
The other substantial results obtained in my work have been communicated in national and international scientific meetings in recent years. Among which, some have been the subject of publications in journals and edited conference proceedings. I would also like to mention that in the wake of this research work, my students defended their Master’s theses and Doctoral thesis.
