I am interested in the wiring of the brain, how neurons grow and form neural circuits and their functions. My research focuses on neural circuitry underlying complex behaviors such as learning, memory, reward related behavior and movement. Disturbances in the neural circuitry of these behaviours contribute to pathophysiology of several neurological disorders such as drug addiction, depression, Parkinson’s disease, Huntington’s disease and Multiple sclerosis. I apply unique and interdisciplinary research tools of molecular biology, optogenetics, chemogenetics and behavioral neuroscience.

Significance:  shows anatomical and functional segregation of AcbSh output pathways to ventral tegmental area pathway promotes relapse whereas whereas the lateral hypothalamus pathway prevents in relapse.

Significance: This paper showed that VP output pathways to the subthalamic nucleus and also to the ventral tegmental area are necessary for reinstatement of alcohol seeking.

Frizzled3 controls axonal polarity and intermediate target entry during striatal pathway development. The Journal of Neuroscience, 35, 14205-14219. IF: 6.747, Cover of The Journal of Neuroscience  

 

Significance: Established the embryonic ontogeny of the two main striatal pathways and identified novel roles for the axon guidance receptor Frizzled3 in uncharacterized aspects of striatal pathway formation

Significance: The first paper using optogenetics in freely moving animals published from Australia. It showed that the striatopallidal pathway, previously thought to be obligatory for all forms of relapse, does not mediate context-induced reinstatement. Instead, a different pallidal input must be important for this relapse.
