"Sumantra Chattarji"

Sumantra "Shona" Chattarji received his Master’s degree in Physics from the Indian Institute of Technology (IIT), Kanpur. He then went on to do a PhD in Neuroscience, under the supervision of Terry Sejnowski, at the Johns Hopkins University and Salk Institute. After post-doctoral research at Yale University and Massachusetts Institute of Technology (MIT), he started his own laboratory at the National Centre for Biological Sciences, India in 1999. His laboratory studies the effects of stressful experiences on synapses, and cells in the amygdala. His research has identified several novel neural correlates of stress-induced plasticity in the amygdala, which are strikingly different from those observed in the hippocampus. His lab also studies synaptic defects and their reversal in Fragile X Syndrome, the leading identified cause of autism.
