RESEARCH INTERESTS
My work focuses on understanding how the brain effectively processes information within a complex environment and identifying neurophysiological factors contributing to information processing deficits within psychiatric populations. I am interested in investigating the neural mechanisms underlying attentional control, specifically, a person’s ability to attend to or ignore specific stimuli within the external and/or internal environment. In addition to neurocognitive behavioral testing, I apply advanced analytical techniques to high-density EEG/ERP data recordings from healthy and patient groups to gain information about the spatiotemporal structure of attentional control.
Currently, I am investigating the neurophysiological characteristics of information processing within the auditory modality by employing a modified mismatch negativity (MMN) paradigm. The modified paradigm is designed to isolate primary sensory perception from attentional processes related to deviance detection. The use of advanced EEG/ERP analytical tools (e.g., PCA, CSD, and BESA) help to disentangle the spatial and temporal overlap among these brain processes. Comparing patient and control groups will test specific hypotheses regarding neurophysiological and cognitive deficits associated with major depressive disorder and schizophrenia. This study also aims to test the effectiveness of utilizing EEG/ERP measures as clinical predictors of successful treatment response in psychiatric disorders.
I have a continuing interest in studying the interaction of emotional regulation and attentional control. Employing the “emotional Stroop” task offers the ability to activate sensory, cognitive, and emotional brain processes simultaneously through the presentation of a single visual stimulus. Stimulus and response related activity associated with detecting a stimulus feature (color) is studied with respect to varying levels of interference from task-irrelevant stimulus features (meaning) and stimulus-elicited emotional reactions.
In order to expand and strengthen the skills I have acquired in my doctoral training thus far, I intend to pursue additional training and experience with other neuroimaging techniques (e.g., fMRI, event-related time-frequency analysis) and clinical populations in a postdoctoral position that complements my research interests.
