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).
