Richard Cole

Richard Cole
MS Student — Psychological Sciences Program — UT Dallas
Email: [email protected]

Richard Cole received his BA in psychology from the University of Arizona and his MS in applied psychology from Walden University in 2013, and MS in psychological sciences from UT Dallas May 2018.

Richard joined the Krawczyk Lab in 2016, with an interest in TBI/rehabilitative techniques, decision-making, and therapeutic methods. His master’s project at UT Dallas used facial recognition technology to determine if there was a visible, emotional aspect of decision-making. As an RA, Richard helped coordinate many aspects of Expedition — a remotely-delivered, cognitive intervention for Veterans with TBI — and outlined procedures for recruiting, the participant experience, and tour-guiding.

In August 2018, he began a PhD program in clinical psychology (military track) at Uniformed Services University in Bethesda, Maryland, where he is currently serving on Active Duty in the Army. His research aspirations include suicide in the military, improving suicide training packages, and stigma in seeking treatment—with an emphasis on the Special Operations Forces community.


Kihwan Han

Kihwan Han, PhD
Email: [email protected]

Dr. Kihwan Han worked in Dr. Daniel Krawczyk’s lab where he analyzed MRI-based neuroimaging data of individuals with traumatic brain injury (TBI) and individuals receiving rehabilitative interventions for TBI. Dr. Han integrated these neuroimaging variables with their neuro-psychological measures.

Prior to joining the Center for BrainHealth, he was a postdoctoral research associate at Washington University in St. Louis for two years after he received his PhD in electrical engineering from Purdue University in 2011. Dr. Han’s research interests include characterizing the brain networks of individuals with TBI and other diseases and disorders as well as utilizing advanced MRI techniques to develop novel methodologies for MRI analysis.

Katelyn Lee

Katelyn Lee
MS Student — Applied Cognition and Neuroscience Program — UT Dallas
Email: [email protected]

Katelyn received her BA in psychology from the University of Mississippi before entering the MS in applied cognition and neuroscience program at UT Dallas where she had joined the Krawczyk lab. Under Dr. Krawczyk, Katelyn’s research aims include work with iMotions on framing effects.


David Martinez

David Martinez
Bass Center at UTSW

David Martinez worked in Dr. Krawczyk’s lab where he assisted research on cognitive performance, behavioral reports, clinical assessments, and neuroimaging data on healthy individuals and those with mild-to-moderate traumatic brain injury (TBI). David has also co-designed an analogical reasoning task to better assess reasoning performance in both healthy and clinical populations. David received his PhD in May 2019.

Before joining the Center for BrainHealth, David worked in clinical neuropsychology and neuroimaging research at The University of Texas Health Science Center in San Antonio. David has a master of science in applied cognition and neuroscience from The University of Texas at Dallas and a bachelor of arts in psychology with a minor in history from Baylor University. David’s research interests include the exploration of brain structure, cognitive changes, and improvements following cognitive intervention in mild-to-moderate TBI, along with finding better techniques to identify neuropsychological deficits in clinical populations.


Jameson Miller

Jameson Miller
Research Coordinator: Center for BrainHealth
Email: [email protected]

Jameson Miller had been with Dr. Krawczyk’s research team since 2014, with primary focus on TBI (Traumatic Brain Injury) within our military and veteran population. His current project is Expedition, a virtual reality game-based TBI intervention. The Expedition project is remotely deployable, meaning that our current and former service members are able to participate from home, and set their own activity schedule to a large degree.

Jameson applies his unique background and experience to be of continued service to our nation’s wounded warriors. His career with the U.S. Army began in the field artillery, later transitioning to medic and laboratory scientist. As a civilian, Jameson continued his work in clinical and forensic pathology and biochemical genetics before attending UT Dallas and later joining the Center for BrainHealth’s commitment to serving our current and former military service members.

Barry was a member of the Traumatic Brain Injury research team and is responsible for data analysis and management. Prior to coming to the Center for BrainHealth he worked in the Office of Institutional Access and Equity at Southern Methodist University as the Data Administration Analyst. Before that he spent 12 years working in the private sector as a Programmer and Data Analyst in the commercial building industry. Barry holds a Master of Science degree in experimental psychology and his research interests include learning, memory, reasoning, social cognition, and statistics.


Adam Teed

Adam Teed, PhD
PhD Student 2010-2017 — Cognition and Neuroscience Program — UT Dallas
Email: [email protected]

Adam has recently earned his PhD in cognition and neuroscience at The University of Texas at Dallas. During his graduate career, he has employed non-invasive neuropharmacological and non-invasive neuroimaging techniques to examine the effects of oxytocin and vasopressin on social perception and on preferences relating to social values. His research interests include using these methods to understand the biological bases of prosocial and antisocial behavior, individual differences in moral character, the role of interoception in social emotions, and social deficits in psychopathology.

Leanne Young

Leanne Young, PhD
PhD Student 2013-2016

After more than 20 years in engineering, Leanne Young took a sabbatical to obtain a doctoral degree in cognitive neuroscience. While studying under Dr. Daniel Krawczyk, Leanne had a dual focus on social neuroscience and virtual reality-based characterization and treatment of functional impairment associated with traumatic brain injury. Immediately upon completing her degree, Leanne joined the Center for BrainHealth to lead its Brain Performance Institute. While there, she led a team of scientists and clinicians in bringing to the public scientifically validated approaches for improving brain health and performance.

Prior to joining the Brain Performance Institute, Leanne ran a division of Applied Research Associates, as a defense contractor, and helped establish human vulnerability as a core business area for that company. Leanne is a nationally recognized expert in blast injury research and worked with the Department of Defense’s Combatting Terrorism Technology Support Office to obtain the first histological evidence of primary blast-induced brain injuries. She worked with the Defense Advanced Research Projects Agency (DARPA) to lead the first clinical trials of blast-induced brain injuries and, working with the Office of Naval Research, she led the development of a computer model for planning the medical response to a blast attack on a ship.

After almost three years leading the Brain Performance Institute, Dr. Young has recently returned to Applied Research Associates, where she is initiating research for the Departments of Defense and Homeland Security in areas related to brain health and resilience, cognitive performance and neuromodulation, and social cognition in human-agent teams.
