I am holding an engineering diploma in mechatronics from the national school of applied sciences of Tetouan (ENSA) class 2016.

Currently, I am a PhD. student at the International University of Rabat. I am developing a system for short-term solar irradiance forecasting and ultimately PV power output forecasting relying on data driven approaches and machine learning algorithms.
