Educational Background
Dr. Amazigh Ouaksel holds a PhD in Environmental Chemistry (2020–2023) from Aix-Marseille University, where he focused on the environmental risks associated with the life cycle of energy technologies, particularly the exposure and impacts of tungsten-based (nano)particles. He earned a Master’s degree (2018–2020) in Waste Management and Polluted Sites (GSDP, MAEVA) from Aix-Marseille University, conducting research at CEREGE. Prior to that, he completed a Master’s in Mineral Resource Valorization (2015–2017) at the University of Bejaia, Algeria. His academic journey has equipped him with expertise in environmental risk assessment, nanoparticle behavior, and sustainable resource management.
Research Experience
Dr. Amazigh Ouaksel has gained extensive research experience in environmental chemistry and nanoparticle behavior. In 2020, he conducted a six-month research internship at CEREGE, Aix-en-Provence, France, studying the fate of TiO₂ and CeO₂ nanoparticles in freshwater ecosystems. In 2019, during a three-month internship at the same institute, he analyzed the hetero-aggregation kinetics of metal oxide nanoparticles with clays. Earlier, in 2017, he undertook a three-month research project at the BBBS Laboratory, University of Bejaia, Algeria, optimizing the physico-chemical parameters of bioleaching for gold ore mineralization. His work contributes to understanding environmental risks and nanoparticle interactions.
