Nathan Clement
Graduate Student

Nathan's research is focused on characterizing and manipulating states of intrinsic motivation and their relationship to learning, information-seeking, and choice behavior. In 2007, Nathan completed his undergraduate studies at Stanford University, where he majored in psychology. For the next three years, he worked at Columbia University before leaving the big city behind to start his graduate career at Duke. He enjoys coffee.


Mai-Anh Vu
Graduate Student

Born-and-raised in Massachusetts, and having completed her undergraduate studies in Cognitive Science at Yale, Mai-Anh decided it was time to venture out of New England, and has since landed here in Durham. Mai-Anh worked in a few different brain labs during and after college, where she gained diverse research experiences: investigating the effects of stress and neuromodulators on prefrontal cortex function in rats, using fMRI to probe memory networks in humans, and using MRI and DTI to characterize brain and cognitive abnormalities in schizophrenia. These seem to be converging here at Duke, where Mai-Anh is pursuing learning and memory research in humans and rodents, under the mentorship of Dr. Alison Adcock and Dr. Kafui Dzirasa. 


Taylor Jackson
Graduate Student

Born outside of Buffalo, NY, Taylor first came to Durham to complete her undergraduate work at Duke, majoring in Neuroscience. She loved it so much; she decided to stay, changing focus from Global Health to Cognitive Neuroscience. In the Clinical Psychology program, co-mentored by Alison Adcock and Joe McClernon, Taylor's interest is in using fMRI to characterize motivation and impulsivity in clinical populations.

Kathryn Dickerson

Katie's research interests lie at the intersection of human reward-related learning, motivation, and memory formation. A particular focus is on investigating the role of dopamine in mediating human memory formation, and the involvement of and connectivity between multiple brain structures (medial temporal lobe, basal ganglia, prefrontal cortex, midbrain) during this process. In collaboration with other members of the Adcock lab, she is addressing these topics using real-time fMRI in both healthy and patient populations. She is particularly interested in understanding if volitionally increasing midbrain dopamine activation can improve motivation and memory formation. Furthermore, she is excited to explore the potential of improving clinical outcomes in a number of disorders where dopamine processing is dysregulated including ADHD, depression, and addiction.

Kimberly Chiew

Born and raised in Northwestern Ontario, Kim completed a BSc in neuroscience at University of Toronto and PhD in cognitive psychology at Washington University in St. Louis before continuing her trajectory south to Duke, where she started a postdoc in the Adcock lab in 2013. Kim's research has focused on examining emotional and motivational influences on cognition using a combination of behavioral, psychophysiological, and neuroimaging methods. In the Adcock lab, Kim is interested in continuing to examine motivational influences on goal-directed and exploratory behavior with a more explicit focus on the role of underlying neuromodulator systems, such as norepinephrine and dopamine.

Jeff MacInnes

When he's not delivering unsolicited lectures on the virtues of living in Michigan's Upper Peninsula, Jeff heads up a number of projects aimed at training individuals to self-induce cognitive states that are most conducive to memory formation. Most recently this is being approached with the use of real-time fMRI - which involves providing participants with real-time neurofeedback of activity within particular brain regions.


Jessica Stanek
Graduate Student

A Bay Area girl having earned her undergraduate degrees in psychology and molecular and cell biology from UC Berkeley, Jessica has left the fog behind in pursuit of memory. Well, memory research that is. She is interested in using fMRI to study hippocampal and dopaminergic midbrain influences on the encoding of novelty and expectancy violation.

Courtnea Rainey

In the broadest sense, Courtnea is interested in improving educational outcomes. Within the context of the motivated memory lab, Courtnea investigated internal states as motivational signals that affect learning and behavioral change. Outside the lab, Courtnea organizes outreach activities and undergraduate research programs to improve science education outcomes in K-16 students.

Betsy Sumner, MD, PhD
Graduate Student
Betsy's PhD research combined pharmacological manipulations in healthy participants with fMRI experiments in schizophrenia patients to study the mechanisms of reward-motivated memory in humans. The overall aim of her work was to contribute to a better understanding of the effects of dopaminergic function and dysfunction on memory in health and disease. Betsy completed her undergraduate studies at the University of South Carolina where she majored in chemistry and minored in mathematics. She completed her MD at the University of Virginia before completing the neurobiology PhD program at Duke. Currently she is in the last year of psychiatry residency at Duke. Her current research and clinical interests converge in the study and treatment of psychotic disorders.
