Rate My Professor Claudio Alonso

Professor Claudio Alonso serves as Professor of Developmental Neurobiology in the Department of Neuroscience, School of Life Sciences at the University of Sussex. He leads the Alonso Lab, applying a neurogenetic approach to investigate the molecular mechanisms that control gene function during the development and function of the nervous system. Utilizing the advanced genetics and mapped neuronal connectome of the Drosophila brain, the lab examines how specific genes and molecular processes influence neural cellular activities across organisms, including humans. Central to this work is the study of Hox genes, an evolutionarily conserved family of transcription factors essential for nervous system formation and function, and RNA regulation, particularly by microRNAs. Research spans neurodevelopmental processes, physiological functions in mature organisms, and the transition from developmental to neurophysiological programs. The lab integrates molecular biology, genetics, transcriptomics, optogenetics, advanced imaging, and behavioral paradigms to uncover principles of neural gene control. Alonso is recognized as a Wellcome Trust Investigator and Wellcome Trust International Fellow, contributing significantly to understanding RNA's role in brain biology.

The Alonso Lab's investigations include the molecular mechanisms of microRNA function in the nervous system, the biological roles of Hox genes and microRNAs in neural development, physiology, behavior, and degeneration, as well as microRNA contributions to neural disease models. Key publications encompass 'A novel post-developmental role of the Hox genes underlies normal adult behavior' (2022), 'MicroRNA-dependent control of sensory neuron function regulates posture behavior in Drosophila' (2021), 'A Single MicroRNA-Hox Gene Module Controls Equivalent Movements in Biomechanically Distinct Drosophila Neurons' (2019), 'The RNA-binding protein ELAV regulates Hox RNA processing in Drosophila' (2014), and 'Fruit fly studies reveal simple genetic system behind complex behaviour' (2019). Alonso actively supervises PhD students and postdoctoral researchers, offering sponsorship for fellowships such as Marie Skłodowska-Curie, Newton International, Human Frontier Science Program, and European Molecular Biology Organization. Former lab members have advanced to prominent roles at institutions including the Francis Crick Institute, University College London, and the MRC Laboratory of Molecular Biology in Cambridge, highlighting his mentorship impact and influence in developmental neurobiology and RNA regulation fields. As a member of Sussex Neuroscience and the Developmental Genetics Research Group, Alonso fosters international collaboration in neuroscience.
