Department of
Biology

Aurnab Ghose read Biology and Chemistry at Presidency College, Calcutta, India followed by a Masters from the University of Leicester, UK. His PhD research was conducted at The Beatson Institute for Cancer Research, UK. Following postdoctoral research at the Dept. of Cell Biology, Harvard Medical School, USA, he joined the faculty of IISER Pune where his group studies the development and function of neural circuits.

Research

Development and functional plasticity of neural circuits

Prof. Aurnab Ghose's group employs quantitative cell biology, biophysical measurements, activity imaging and behavioural analysis to explore two aspects of the nervous system.

Theme 1: The ontogeny and homoeostasis of neural circuits, with emphasis on cytoskeleton remodelling and cellular biomechanics

Theme 2: Functional modulation of neural circuits by neuropeptides and integration of internal states with behavioural outputs
