Principal Investigator

null I received my Ph.D. from the University of Illinois in 1995, and spent time as a postdoc at Stanford University and a faculty member at the MGH-NMR Center/Harvard Medical School before moving to UCLA in 2002. In 2009 I moved to the University of Texas at Austin to become Director of the Imaging Research Center and Professor of Psychology and Neurobiology.  My research interests are very generally centered around the questions of how new skills are acquired, how existing skills are expressed, and how people exert executive control during thought and behavior. We examine these questions using functional brain imaging techniques, particularly functional magnetic resonance imaging (fMRI). I am also interested in conceptual and methodological issues surrounding the relation between cognitive and neural processes. Our research is strongly focused on translation of basic cognitive neuroscience into the clinical domain, with collaborations on studies of schizophrenia, ADHD, Tourette Syndrome, and drug addiction.

Faculty

null I received my PhD in Biostatistics from the University of Michigan in 2006, where I worked with Tom Nichols on projects involving group BOLD fMRI data analysis as well as single subject Arterial Spin Labeling fMRI. My current focus is on developing a tool that will calculate power for group fMRI experiments, which will be helpful in designing future experiments.

Postdocs

null I received my PhD from Stony Brook University in 2008, where I worked with Turhan Canli. My dissertation research focused on the neurogenetic bases of impulsivity, specifically response inhibition, in healthy adults. Working with both the Poldrack Lab at UT and Nelson Freimer’s Neurobehavioral Genetics lab at UCLA, I am interested in integrating neuroimaging and genetics to better understand cognitive control, particularly in the context of neuropsychiatric disorders. I am heavily involved in research that is part of the Consortium for Neuropsychiatric Phenomics at UCLA.

Eliza Congdon

null I received a Ph.D. in cognitive psychology from UT Austin in 2010, where I worked with Brad Love, Todd Maddox, and Alison Preston on projects related to category learning. My current research involves using cognitive models to interrogate imaging data from category learning and decision making experiments.Personal Web Site

null After completion of PhD work under the supervision of Drs. Yasushi Miyashita and Seiki Konishi at the University of Tokyo School of Medicine, I worked with Dr. Todd S Braver at Washington University in St. Louis. I am interested in how executive functions interact with and/or contribute to decision-making.

Koji Jimura

null I completed my PhD in Tel Aviv University, under the supervision of Daphna Joel, co-supervised by John O’Doherty from Caltech and Trinity college Dublin. My dissertation research focused on reinforcement learning in the striatum: how these signals are correlated with learning in simple decision making in healthy subjects and how these signals are affected by the dopamine depletion in Parkinson’s disease. In the Poldrack lab I am studying the connectivity profile of the reward-based decision making network and the relations between risky decision making and response inhibition.

Tom Schonberg

I am interested in how the brain implements flexible behavior by adjusting different aspects of the decision process.  I employ a translational approach that combines computational models of decision making, functional neuroimaging, and clinically-relevant populations (e.g., individuals with high levels of anxiety).  This research seeks to develop a working knowledge of the behavioral and neural correlates of different aspects of decision making, which can be used to gain a better understanding of maladaptive decision biases associated with anxiety and depression.  The goal is to understand how and why such biases develop, how they are represented in the brain, and how they can be reduced or overcome through cognitive retraining.  My current work is generously funded by the National Institutes of Health (NIH grant F32 MH096522-01A1).

null I received my PhD in Neuroscience and Cognitive Sciences from the University of Maryland in 2011, under the supervision of Nathan Fox. My research interests are broadly centered around understanding how individuals use information about punishment and reward to guide behavior, and how the neural circuitry involved in these processes changes across development.

Graduate Students

null I am a graduate student in the Neuroscience (INS) program. I graduated in 2006 with an Sc.B. from Brown University. I then joined Dr. Brad Dickerson’s neuroimaging lab at MGH in Boston where we used structural MRI to identify the anatomic effects of aging and neurodegenerative disease. In the Poldrack lab, I am interested in investigating ways to influence human behavior during decision making using behavioral paradigms and fMRI.

Akram Bakkour

null I am a graduate student in cognitive neuroscience area at UT-Austin. My general research interest is how people make decisions in various contexts. I got my master degree in visual neuroscience at National Taiwan University, where I studied facial expression classification with psychophysics models. I hope to combine mathematical models and fMRI techniques to explore the neural mechanisms of perceptual, economic, and social decision-making in the Poldrack lab.

Mei-Yen Chen

 

null I am a graduate student in the Institute for Neuroscience doctoral program. My research is presently focused on the interaction of effort costs and reward in decisions. I previously investigated neural representation of complex objects in Leslie Ungerleider’s laboratory at the NIMH and the role of nucleus accumbens in appetitive behavior at Macalester College. I received a B.A. in Cognitive and Neuroscience Studies from Macalester in 2007.

Staff

null I am a Research Assistant at UT Austin’s Imaging Research Center. I graduated from Portland State University in 2007 with a B.S. in Psychology as well as a B.S. in General Sciences. After receiving my degree, I worked for two years as an RA at Oregon Health and Science University. I worked in both the Department of Biomedical Engineering, under the direction of Tamara Hayes and in the Alzheimer’s Disease Center, under the direction of Jeffrey Kaye, where we studied the behavioral and cognitive effects of aging. My future goals are to become a part UT Austin’s INS graduate program.

Brenda Gregory

 

null My main interests are focused on cognitive neuroscience and the neuropsychology of implicit skill learning. We explore implicit skill learning from memory formation to consolidation and how this process is affected by age, sleep, and disorders such as autism, SLI, dyslexia, Huntington’s disease, Mild Cognitive Impairment, and Spinocerebellar Ataxia. These studies could lead us not only to a deeper understanding of this learning mechanism but also to discover how we rewire skills and boost habit change.
