Richard Cole

Richard Cole
MS Student — Psychological Sciences Program — UT Dallas
Email: Richard.cole@usuhs.edu

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

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.

PhD Student — Cognition and Neuroscience Program — UT Dallas
Email: mehmet.gunal@utdallas.edu

Before joining the cognition and neuroscience program, Mehmet Günal received his BS and MS degrees in electrical engineering from Purdue University, with a specific focus on Digital Signal Processing. His prior brain imaging research experience involved characterization and removal of respiratory artifacts for fMRI, investigating fiber connectivity between Broca’s and Wernicke’s area among stuttering children using DTI, and developing a brain-computer interface using a wheelchair and an EEG cap.

His prior behavioral research experience involved an evolutionary approach to adaptive memory and learning, and exploring the survival processing of face recognition and context information. His current research in Dr. Krawczyk’s Reasoning Lab investigates the attention control by measuring lateral versus medial frontopolar cortex (BA 10) and LC-NE network activity using simultaneously acquired fNIRS and pupillometry response.

Matt Kmiecik

Matt Kmiecik, PhD
Cognition and Neuroscience Program — UT Dallas

Matt completed his graduate training under the mentorship of Dr. Krawczyk where he studied executive dysfunction in chronic-phase traumatic brain injury, human thinking and reasoning, and volitional control of semantic processing. After earning his PhD in cognition and neuroscience from UT Dallas, he began a postdoctoral research fellowship at Northshore University HealthSystem’s Evanston Hospital (Evanston, IL) studying mechanisms of chronic pelvic pain.

Prior to graduate school, Matt received his BS in psychology: natural sciences from Loyola University Chicago. He enjoys visualizing and analyzing data, teaching others how to program in R, and watching Chicago sports, especially the Blackhawks.

Jameson Miller

Jameson Miller
Research Coordinator: Center for BrainHealth

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.

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.
