Dr. Padmanabhan's research aims to understand principles of neuronal function in the mammalian brain using experimental and computational methods with a focus on uncovering the biological bases of psychiatric disorders. Work in the Padmanabhan lab uses multi-electrode electrophysiology, induced-Pluripotent Stem Cell (iPSC) technology, imaging, and theoretical models to address three outstanding questions in neuroscience.

1) How does the brain represents features of the world via patterns of neuronal activity?
2) How does memory and experience shape the process of sensory perception?
3) How are these functions disrupted in neurological and psychiatric disorders?
