Research interests

I am a neuroscientist and my research interests focus on the neural mechanisms by which subcortical brain circuits encode goal-directed learning. By implementing innovative high-throughput fluorescence microscopy and computational image analysis, I have made several important contributions to the understanding of the functional architecture of the mouse striatum. Besides my work on the most fundamental aspects of striatal functional neuroanatomy, I also investigate how normal ageing negatively impacts specific aspects of learning and motivation in mice.
