After receiving his PhD in experimental psychology from Georgia
Tech, Dr. Rypma did postdoctoral work focusing on neural imaging
at Stanford and the University of Pennsylvania. He also brings
his expertise in fMRI (functional magnetic resonance imaging)
to UT Southwestern Medical Center (UTSW), and he has been
appointed by Dean Bert Moore as the faculty liaison between
UT Dallas and UTSW.
Dr. Rypma came to the Center from Rutgers University. “I
had never imagined myself living in Dallas, Texas, but once
I came here and saw all the resources being committed to neuroscience,
I knew it was a good place for me,” he says. “Neuroscience
isn’t something you can do in a small way. It has to
be done big, and it has to be done right, so I was really
impressed with Center for Brain Health, UT Dallas, and UTSW.”
Dr. Rypma’s research is aimed at exploring the cognitive
and neurobiological mechanisms of human memory and how those
mechanisms are affected by aging and disease. He uses functional
magnetic resonance imaging (fMRI) to observe the activity
of younger and older adults as they perform cognitive tasks.
fMRI is still a relatively new method for studying brain activity
and much work remains to be done to perfect it, especially
when comparing different populations like young and old. Thus,
one focus of Dr. Rypma’s work has been the development
of fMRI experimental methods to facilitate cross-population
comparisons of neural activity.
He has published extensively cognitive and neurobiological
mechanisms of human memory, including high-profile publications
in Proceedings of the National Academy of Science, Nature
Neuroscience, Cortex, and Neuroimage. Click

Dr. Ilana J. Bennett is currently a Postdoctoral Research
Fellow in Dr. Bart Rypmas lab at the Center for Brain Health
and the School of Behavioral and Brain Sciences at the University
of Texas at Dallas and at the Department of Psychiatry at
the University of Texas Southwestern Medical Center. She received
a PhD in Psychology with a concentration in Lifespan Cognitive
Neuroscience from Georgetown University in 2009. For the past
8 years, her research has focused on cognitive and neurobiological
changes associated with healthy aging with an emphasis on
understanding the neural mechanisms underlying age-related
differences in learning and memory.

Dr. Joanna Hutchison is currently working as a Postdoctoral
Research Fellow with Dr. Bart Rypma at the Center for BrainHealth
and the School of Behavioral and Brain Sciences at the University
of Texas at Dallas and at the Department of Psychiatry at
the University of Texas Southwestern Medical Center.
Research Interests: Cognition and circumstances that affect
cognition, such as aging, traumatic brain injury, and psychiatric
illness (e.g., schizophrenia, bipolar disorder, depression);
auditory processing; fMRI.

Dr. Colby completed a B.S. in Biology Composite Teaching
at Brigham Young University with a minor in English. Following,
she attended Baylor University were she received her M.A.
and Ph.D. in Neuroscience with a minor in Assessment. Dr.
Colby's research passion has always been learning and memory.
Particularly, she is interested in the physiology of memory
and individual differences.

Dr. Meghana Karnik-Henry is currently a Postdoctoral Research
Fellow working with Dr. Bart Rypma at the Center for Brain
Health and the School of Behavioral and Brain Sciences at
the University of Texas at Dallas. In 2009, she completed
her Doctorate in Neuroscience from Washington University in
Saint Louis. Prior to that, she graduated from Rutgers, The
State University of New Jersey with a BA in Cell Biology and
Neuroscience. Her background is in functional neuroanatomy
and cognitive neuroscience. In graduate school, Dr. Karnik-Henry
gained experience in processing structural magnetic resonance
imaging data and she has delineated and mapped several structures
of the medial temporal lobe in healthy control subjects, schizophrenia
patients and their unaffected younger siblings. Her doctoral
dissertation involved identifying differences in medial temporal
structure across the above four groups, and relating her structural
findings to cognitive data collected from these same subjects.
By working with Dr. Rypma, Dr. Karnik-Henry looks forward
to gaining experience in functional neuroimaging and aging
research related to working memory. She hopes to combine her
structural imaging skills with the functional imaging training
she will receive at the Center for Brain Health so she may
better understand how variation in brain structure relates
to cognitive function.
