    1. Mechanism of action of antidepressant, anxiolytic, and antiaggressive drugs in several mouse models of affective/cognitive disorders, including aggressive behavior, schizophrenia, and PTSD
    2. Developing new therapies for PTSD and anxiety disorders
    3. Epigenetic mechanisms and psychiatric disorders, including schizophrenia
    4. Understanding emotional brain circuits that mediate cognitive and affective processes in PTSD mouse models
    5. Physiological role of neurosteroid allopregnanolone on GABAA receptor function
