Rouabhi Nesrine is a PhD student at the University of Science and Technology Houari Boumediene (USTHB), specializing in biodiversity and environmental science. Her research focuses on the study of aquatic ecosystems, particularly crustacean decapod species, such as crabs, and their role in assessing water quality and pollution. She uses a multidisciplinary approach, integrating ecological, biological, genetic, morphometric, and statistical methods to understand the effects of physico-chemical parameters on aquatic environments. Through this interdisciplinary research, she aims to provide valuable insights into the health and sustainability of aquatic ecosystems, contributing to efforts in environmental conservation and management
