Denis Hamad is professor at the University of Littoral Côte d'Opale since 2002. He obtained a HDR (Habilitation à Diriger la Recherche) degree in neural networks for unsupervised pattern classification and a Ph.D. degree in detection and validation of measurements in complex systems from the University of Lille 1 Sciences and Technologies-France in 1997 resp. in 1986.
Between 1998 and 2002, he was Professor at University of Picardie Jules Vernes, Amiens-France and Head of the CREA Laboratory. His main research interests are in: Machines learning, unsupervised classification, image and signal segmentation.
Since 1993, he has been involved in many industrial projects related to machine learning systems: Glass bottles inspection, wind turbine supervision, robot control, fault detection and diagnosis systems, transport security and more recently monitoring of marine environment ecosystem.
Actually, his research is in the area of signal processing and machine learning for "environment, coastal environment, and sustainable development". He is involved in the Interreg 2 Seas DYMAPHY Project "Development of a DYnamic observation system for the assessment of MArine water quality, based on PHYtoplankton analysis". He managed the PhytoClas project which has been selected as innovative project and supported by the university ULCO. PhytoClas has the objective of characterization and classification of phytoplankton by Cytometry signal analysis and image processing. He managed the CLASPEC project "Spectral Clustering for Color Image Segmentation and Audio Signals". CLASPEC has been supported by "Graisyhm research federation". He managing the REPAR project "Représentation Parcimonieuse et Apprentissage Dynamique pour le signal et l'image". REPAR 2014-2017, is supported by AIRR Regional found.
