Research Interests

Understanding the epigenetic or chromatin remodeling mechanisms in complex disorders of brain and behavior, the neuropsychiatric diseases, in particular, the molecular and cellular mechanisms underlying etiopathophysiology of affective disorders such as depression, anxiety and post-traumatic stress disorder (PTSD). Using rodent models we study how chronic environmental perturbations such as stress cause alterations in circuitry controlling mood and emotions, by inducing lasting changes in function of many genes via events at the chromatin level (i.e., epigenetic mechanisms).Understanding the epigenetic regulatory mechanisms in neural stem cell biology, i.e. neurogenesis and gliogenesis in adult mouse brain, using both in vitro and in situ approach; this approach might also give us clue to the etiopathology of brain tumors such as astrocytoma or glioblastoma, etc. Our earlier expertise in apoptosis and tumor biology research and the latest one in genome-wide epigenenomics come together in zeroing in on the etiopathology of cancer of nervous system origin.
