Molecular interactions between neurons and glial cells are vital for proper functioning of nervous system across species. Interactions between neurons and glial cells are central in processes such as ensheathment of axons, formation of axo-glial junctions, and maintenance of functional blood-brain and blood-nerve barriers. I use the Drosophila nervous system to investigate the molecular basis of axonal ensheathment. Using genetic, cell biological and biochemical approaches, we have identified several proteins that have fundamental roles in neuron-glial interactions underlying the process of ensheathment of axons. Our studies in Drosophila are relevant to elucidate the mechanisms regulating vertebrate myelination in health and disease.

Another area of my research interest involves the study of synapse formation and function. Work in our laboratory has generated mutations in two key synaptic cell adhesion molecules, Neurexin and Neuroligin in Drosophila that connect the pre- and postsynaptic terminals of the synapses. In humans, mutations in Neurexin or Neuroligin genes are implicated in Autism Spectrum Disorders and other cognitive disorders. I am interested in deciphering how Neurexin/Neuroligin mediate trans-synaptic signaling and shape neural networks to process and refine information.
