Principle Investigator:

Wendy Heller, PhD

Wendy Heller is Professor of Psychology in the Clinical/Community Division, former Director of Clinical Training and Department Head in the Psychology Department, and a part-time Beckman Institute faculty member in the Cognitive Neuroscience Group. As of 2014 she was appointed Provost Fellow with a special focus on campus diversity. She holds a B.A. in Spanish and Psychology with Honors from the University of Pennsylvania and an M.A. and Ph.D. in Biopsychology from the University of Chicago. Her research investigates the neural mechanisms associated with emotion-cognition interactions and their implications for psychopathology. She is particularly interested in examining cognitive and emotional risk factors associated with the development or maintenance of anxiety and depression. She uses behavioral and neuroimaging methods such as neuropsychological task performance, functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and event-related potentials (ERPs).  She draws on psychological theories to model how fundamental emotion and personality constructs can be mapped onto brain systems to clarify the neural mechanisms of emotion and psychopathology. In turn, the neuropsychological  and neuroimaging findings are used to inform psychological theories of emotion and psychopathology. Her work has been funded by the National Institute of Mental Health (NIMH).

Joel completed his undergraduate degree at Harvard University earning a bachelor’s in Government and Certificate in Health Policy. As a graduate student at the University of Illinois at Urbana-Champaign, he studies the ontology of psychological distress. His work focuses on understanding how relational schemas function as causal mechanisms that link early trauma to adult psychopathology. His additional interests lie in psychological healing processes, philosophy of mind, and philosophy of science.


Megan Finnegan


Megan obtained a B.S. in Cognitive Science from University of California, Merced. Her undergraduate research with Dr. Anne Warlaumont focused on the development of infant precursors of language using neural-level models of dopamine-modulated spike-timing dependent plasticity and articulatory synthesizers. Early PhD research focused on using fMRI to characterize the neural changes associated with a mindfulness-based intervention. Megan’s current research interests include utilizing neuroimaging data such as fMRI to specify the architecture of artificial neural networks. This is to understand how large-scale brain networks are instantiated at the neural population level. She hopes to apply these insights to develop a more comprehensive understanding of how clinical interventions such as meditation training exert their therapeutic effects.

Aminda O’Hare, PhD


Aminda is now an Assistant Professor at University of Massachusetts at Dartmouth after a postdoctoral position in the Heller/Miller lab. She comes from a diverse background of training within the field of cognitive neuroscience, and this has prepared her to bridge areas of interest between divisions of psychology. She is broadly interested in the intersection of cognition and emotion. Specifically, she is interested in how individual differences in sensitivity to emotion bias cognitive processing. For example, she has found that different types of anxiety and different genotypes can predict differences in cognitive processing at early stimulus detection, attentional shifting, attentional inhibition, and much later information search and decision-making.

simona_large (1)Simona Buetti, PhD

Simona is a Research Assistant Professor at the University of Illinois at Urbana-Champaign. She is interested in understanding visual attention, emotion-cognition interactions, and response interference effects in individuals who vary in terms of their personality and emotional temperament (normal, at-risk for depression, at-risk for mania, at-risk for phobia). Some of her recent work focuses on the relationship between cognitive load, task difficulty and visual distractibility. Simona has also recently proposed a new two-stage theory of visual attention that is based on the premise that attention works to diminish uncertainty in a scene. Using behavioral and imaging methods, Simona is pursuing two lines of research on emotion-cognition interactions. The first focuses on the effects of stimulus relevance and its impact on emotion processing and attentional control. The second aims at understanding how the subjective experience of control over experimental events (real and illusory) changes the way participants respond to emotional events.
