About me

I am Professor at the University of Batna 2, Algeria. My research interests include: Photovoltaic Devices, Nano- and Microelectronics, Soft-Computing-Based Modeling, Quantum Structures and Software Design (PSPICE, Cadence).

Together with my research group I developed new intelligent-hybrid simulators, by introducing the soft-computing and analytical modelling approaches, for future microelectronic and ULSI nanoscale device simulators (nano-processors, nono-memory cells, solar cells, …). These simulators allow to study and improve the accuracy and the computational time efficiency of the nanoscale applications. In addition, the group is interested to develop new fuzzy logic and neural-space-mapping-based approaches for possible implementation on Field-Programmable Gate Arrays (FPGA). These approaches can greatly improve the nanoscale circuits' simulator performance and microelectronic device simulation techniques. The developed approaches are now widely employed in many research laboratories.


Current projects

     

  • Member of the AGYA Working Group Energy, Water and Environment (EWE):
    My role, as member of EWE Working Group, is to provide a review of the research that has been conducted on the use of photovoltaic technology for solving energy problems in Germany and Arab countries. The review will also include some of the real-world statistics and will conclude with some of the potential paths for future research in photovoltaic-based applications.
