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).

Mike Niznikiewicz

Mike received his B.S. in Psychology and Neuroscience from the University of Massachusetts – Amherst. He gained a background in experimental psychology and functional magnetic resonance imaging (fMRI) working as a research assistant in Dr. Mauricio Delgado’s Social and Affective Neuroscience lab studying the neural correlates of reward related learning. His current interests lie in the ways that brain functions are affected by vulnerabilities to psychopathology. Specifically, how performance in cognitive control tasks is affected by emotional distractors as a function of dimensional measures of psychopathology. Furthermore, he is also interested in how typical responses to feedback (e.g., rewards or punishments) on such tasks vary as a function of these same measures. Under the guidance of Dr. Wendy Heller, Mike hopes to be able to expand the understanding of psychopathology and ultimately inform more effective therapeutic practices with his work.

italy2Paul Sharp

Paul completed his undergraduate work at Temple University’s honors college, double majoring in psychology and political science. At Temple, Paul worked with Dr. Jason Chein and Dr. Laurence Steinberg in Temple’s Neurocognition Lab, investigating the neural correlates of reward sensitivity in adolescents and specifically how social context and mood affects said neural circuits and concurrent behavior. Following graduation in 2013, Paul came to Illinois to pursue his Ph.D., and his interests have begun to take shape since he arrived this past fall. Working with Dr. Brad Sutton, a bioengineer on campus, he is learning to use cutting-edge diffusion imaging techniques to track white matter pathways and their development in cognitive-affective circuits relevant to depression and anxiety, and will pursue a neuroengineering minor to support this goal. Paul plans to implement this methodology in an upcoming study investigating how mindfulness affects childrens’ neural development, with the theory in mind that cultivating mindfulness practice developmentally early promotes skills such as metacognition, sustained attention, and cognitive control, which may significantly mitigate and perhaps prevent future onset of anxiety and depression. Additionally, Paul is interested in how the brain represents emotion, and plans to use other neuroimaging techniques such as multivoxel pattern analysis to investigate theories of emotion representation and how such data can help refine the Heller lab’s model of anxiety which differentiates anxious apprehension from anxious arousal.

 Sima_Owl_2M. Sima Finy

Sima is a Ph.D. student in Clinical/Community Psychology at UIUC. She received her B.S. from The Ohio State University and her M.A. from UIUC. Sima’s program of research applies a multiple-levels-of-analysis approach (e.g., genetic, neuroendocrine, personality, neuropsychological, behavioral) to examining how individual differences in disinhibition contribute to the development of multiple forms of psychopathology, particularly during adolescence. Her master’s thesis examined how adolescents’ disinhibited behaviors and cortisol reactivity are influenced by interactions between psychosocial stress and personality traits to uncover how developmental changes are related to adolescent psychopathology. For her dissertation, Sima is investigating the effects of genetic risk and executive functions on ADHD traits in a large sample of youth. Her long-term goals are to identify mechanisms that contribute to adolescent psychopathology and, in turn, identify targets for intervention.

Annie received her B.S. In Neuroscience and French from the University of Michigan, where she worked as an undergraduate research assistant with Dr. Kelly Ryan and Dr. Bruno Giordani at the Michigan Alzheimer Disease Research Center on projects related to caregiver burden. Following graduation, she gained experience with fMRI and neuropsychological assessment as a research assistant for Dr. Scott Langenecker at the University of Michigan and the University of Illinois at Chicago. Annie’s current interests lie in studying how emotional attention differs among individuals at-risk for mood disorders. Specifically, she is working with Dr. Simona Buetti on an fMRI study that investigates the effect of perceived control in reaction to emotional events in subjects with depression or mania. Additionally, Annie is interested in assessing the effects of mindfulness meditation interventions on measures of working memory and cognitive control.

Aminda O’Hare, PhD

umassd_photos_000051374

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.
