Research Interests:

Impact of emotion on perception and attention

Transdiagnostic neural markers of psychotic disorders

Current Research:

The aim of my research is to understand how and why we prioritize emotional stimuli and how this prioritization is impacted by anxiety. To answers these questions, my research focuses not just on how the brain processes emotional stimuli but also on how the brain generates predictions regarding emotional stimuli. Emotional stimuli do not occur in a vacuum; rather, they typically occur embedded in contexts filled with cues that predict their identity and location. Our brain can utilize information provided by these cues or by the spatial regularities within the context itself and predict upcoming threat. For example, while walking on a desert trail, prior learning regarding the context or park signs warning of rattlesnakes may lead us to look out for rattlesnakes, resulting in their faster and more accurate detection. In my lab, we use cognitive behavioral tasks, computational modeling, functional magnetic resonance imaging (fMRI), a range of imaging analyses techniques (univariate and multivariate) and different modalities (vision and olfaction) to examine ways in which the brain predicts emotional stimuli even before they happen, and how these prestimulus predictions enhance subsequent perception and attention. T he examination of prestimulus anticipatory processing is particularly important in case of anxiety. The clinical literature has distinguished anxiety from fear by emphasizing the anticipatory nature of anxiety. However, o ur basic understanding of the neurobiology of anxiety is based, not on prestimulus anticipatory response, but on actual neural response to threatening stimuli. Hence, research in my lab aims to understand how anticipation of threatening stimuli impacts attention/perception and contributes to the development and maintenance of anxiety.

While it is highly adaptive to use prior information regarding threat to perceive and attend to stimuli in our environment, if these stimuli pose no immediate danger to our well-being, it is equally adaptive to override their distracting effects and remain focused on ongoing tasks. Another line of research in my lab examines how we use cognitive control strategies to remain task-focused in the presence of emotional distractors. This line of research is particularly relevant to psychotic disorders that are characterized not just by neural deficits related to emotion perception but an inability to stay task-focused in the presence of emotional distractors. In collaboration with Dr. Roman Kotov in Department of Psychiatry, we are examining how these emotion-cognition interactions relate to symptom dimensions as well as global functioning, trasdiagnostically across different psychotic disorders.
