RESEARCH INTERESTS: Our lab investigates the impact and mechanisms whereby stress affects brain function and cognition, with a focus on learning and memory processes, social behaviors and psychiatric disorders - such as anxiety, depression and pathological aggression. Over the past years, we have worked on the development of an integrative overview of how stress impacts learning and memory and characterized key mediating mechanisms (glucocorticoids, cell adhesion molecules, glutamate receptors). We have also identified key mechanisms connecting stress and psychopathology, and studied the modulatory role of anxiety trait. Currently, our lab focuses efforts in the understanding of how stress affects the social brain. Since stress is an important modulator of brain structure and function, one research line in the lab studies the involvement of synapse-associated cell adhesion molecules (neuroligins, nectins) in the mechanisms that translate stress effects on altered social behaviors. We are also interested in identifying the mechanisms that lead from early life exposure to traumatic stress to the development of violent behaviors, including changes in neurodevelopmental trajectories and epigenetic mechanisms involved in epigenetic transmission. Another main project in the lab addresses the impact of stress and anxiety trait in the development of social hierarchies, with a focus on the role of social neuropeptides (oxytocin and vasopressin), the mesolimbic system, and cellular metabolism. These animal studies are currently being complemented by approaches in humans in the emerging field of behavioral and neural economics.
