Lab Personnel


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,
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.

If you're potentially interested in joining the lab as a graduate student, research
assistant or intern, contact Alison Adcock.


Shabnam Hakimi

Shabnam is interested in the neuroscience of behavior change, specifically
how computational neuroimaging methods can be used to identify novel,
neurally-informed targets for individualized behavior change. Prior to joining
the lab, she completed her Ph.D. at Caltech, where she investigated the neural
mechanisms supporting cognitive control, focusing on prefrontocortical signals
and their ability to predict behavior. Shabnam is particularly interested in
translating insights from the neuroscience of behavior change to both healthy
and clinical populations; she is currently examining interactions between
motivation, perception, and decision making using real-time fMRI
neurofeedback targeting motivational circuits in ADHD. 

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.

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.


Laura Lerebours
Lab Manager

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
Graduate Student

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 parti
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.
