I am currently Associate Professor (HDR) at the Digital Research Center of Sfax (CRNS) and the head of the DeepVision research team. I am also a member of the SM@RTS Laboratory. I obtained my accreditation to supervised research (Habilitation Universitaire) in 2021 from the university of Sfax, my Ph.D. degree from the university of Rouen in 2009 and my engineer's degree from the National Engineering School of Sfax (Tunisia). Before joining CRNS, i was assistant professor at ISIMA and postdoctoral researcher at ITESOFT and LITIS

I am certified as an official instructor and ambassador from the NVIDIA Deep Learning Institute. My main research areas concern deep learning, document processing and recognition, data fusion, and computer vision. I have participated in several research projects and technology transfer projects. I have published more than 60 papers in international conferences and journals. I am also a reviewer for several international conferences and journals in the field of pattern recognition and computer vision.

The MedPRAI proceeding book is online 

This book constitutes the refereed proceedings of the 4th Mediterranean Conference on Pattern Recognition and Artificial Intelligence, MedPRAI 2020, held in Hammamet, Tunisia, in December 2020.​ Due to the COVID-19 pandemic the conference was held online.The 24 revised papers presented were thoroughly reviewed and selected from 72 submissions. The papers are covering the topics of recent advancements in different areas of pattern recognition and artificial intelligence.


New accepted paper in Applied Soft Computing

Our paper "Federated learning for COVID-19 screening from Chest X-ray images" is accepted in Applied Soft Computing journal, Mars 2021. Impact Factor=8.263, Q1

In this work, we present a collaborative federated learning framework allowing multiple medical institutions screening COVID-19 from Chest X-ray images using deep learning without sharing patient data. We investigate several key properties and specificities of federated learning setting including the not independent and identically distributed (non-IID) and unbalanced data distributions that naturally arise.
