We are interested in unraveling molecular mechanisms underlying gene expression changes in psychopathological states.

The main focus of our research is on the role of gene x environment interaction in modulating adult behavioral phenotypes. We are conducting molecular, anatomic, and behavioral studies on animal models of depression-like behaviors and animal models of cognitive dysfunctions to study the role of epigenetic changes in gene expression in psychopathological states.
