My research focuses on understanding how emotional events modulate cognitive processes in the human brain. We aim to identify brain regions that encode the emotional properties of sensory stimuli, and to show how these regions interact with neural systems supporting social cognition, executive control, and learning and memory. To achieve this goal, we use a variety of cognitive neuroscience techniques in human subject populations. These include psychophysiological monitoring, functional magnetic resonance imaging (fMRI), virtual reality, and behavioral studies in healthy adults as well as psychiatric patients. This integrative approach capitalizes on recent advances in the field and may lead to new insights into cognitive-emotional interactions in the brain.
