Biography

Florin Dolcos is an Assistant Professor in the Department of Psychology and a full-time faculty member in the Beckman Institute’s Cognitive Neuroscience Group. His research investigates the neural correlates of emotion-cognition interactions in healthy and clinical populations. Dr. Dolcos performed his PhD research in cognitive and affective neurosciences at the University of Alberta’s Centre for Neuroscience and Duke University’s Centre for Cognitive Neuroscience, and his post-doctoral training in cognitive, affective, and clinical neurosciences at Duke University’s Brain Imaging and Analysis Center. Dr. Dolcos joined the University of Illinois following an Assistant Professor appointment in the University of Alberta’s Department of Psychiatry.

Honors

Dr. Dolcos received a NSERC Post-Doctoral Fellowship from the Natural Sciences & Engineering Research Council of Canada (2006), the Laird Cermak Award for Early Contributions to Memory Research from the Memory Disorders Research Society (2006), a Young Investigator Award from the National Alliance for Research on Schizophrenia and Depression (2007), and a CPRF Award from the Canadian Psychiatric Research Foundation (2008).

Research

Florin Dolcos’ research interests concern the neural correlates of affective-cognitive interactions in healthy and clinical populations, as studied with brain imaging techniques (e.g., fMRI and ERP). Florin Dolcos’ program can be divided into the following two main directions:

1. Basic research investigating the neural mechanisms underlying the impact of emotion on cognition in healthy participants. This direction focuses on identifying the mechanisms that are common to both the enhancing and the impairing effects of emotion on cognitive functions (e.g., enhanced memory for emotional events and enhanced susceptibility to emotional distraction, respectively), and on identifying the mechanisms that dissociate these two opposing effects of emotion on cognition.

2. Translational research investigating the role of individual differences in mediating the emotion-cognition interactions. This direction focuses on identifying the neural circuitry responsible for differential ability to experience, remember, and regulate emotions associated with age-, gender-, and personality-related differences, in both healthy and clinical cohorts.

Dr. Dolcos’ research group investigates these issues using brain imaging methods (fMRI, ERP) in conjunction with other psychophysiological (electrodermal responses) and behavioral assessments (performance in cognitive and neuropsychological tasks, personality questionnaires).

Investigation of these issues has direct implications for understanding the neural correlates of affective dysregulation observed in mood and anxiety disorders, which are characterized by pathological biases in processing negative emotions, intrusive recollection of distressing events, and increased emotional distractibility.
