The precise elaboration and specification of neuronal circuits is at the basis of any properly functioning nervous system. For circuits to be established, neurons form remarkably accurate connections with their target cells during development. How are these connections established? Neurons send out cell protrusions called axons, which navigate in a complex environment to reach their exact target, a process known as axon guidance. Understanding the key molecules that induce the formation of such precise circuits is crucial, because any failure in this process, either during development or following injury or disease, impairs the proper function of the nervous system. Axons

Research directions

We investigate the cellular and molecular mechanisms that enable axons to grow and to accurately find their targets during development. We are particularly interested in understanding the role of non-coding RNAs in this process.
