Areas
I am interested in sex differences and sex hormone effects on emotional learning and anxiety behavior, and in the development of animal models of endocrine-related psychopathologies including post-traumatic stress disorder and post-partum depression. In my lab we use methodology that includes: discrimination fear-learning, acoustic startle, intracranial drug and hormone infusion, in situ hybridization, immunocytochemistry, to explore these subjects at all stages from the behavioral down to the system and molecular levels.
