We are a cognitive neuroscience lab studying the mental processes involved in reasoning, decision-making, and memory. We study the relationship between brain and behavior in healthy individuals and people who have psychiatric or neurological impairments. We use behavioral measurements, cognitive interventions, and neuroimaging techniques in our research. We are located at the Center for BrainHealth at The University of Texas at Dallas and the Department of Psychiatry at The University of Texas Southwestern Medical Center.

Research Assistant

Lauren Kim

Lauren M. Kim
Email: Lauren.Kim@utdallas.edu

Lauren Mina Kim is currently a research assistant working in Dr. Daniel Krawczyk’s lab. Her educational background includes a BS degree in biomedical engineering with a minor in molecular biology, as well as a BS in psychology from The University of Texas at Dallas.

Prior to joining the Center for BrainHealth, Lauren worked as a multi-disciplinary systems engineer for Raytheon where she assisted with the designing of smart missile systems and flight radar projections. In her off hours, she works as an executive functions coach for adolescents/adults suffering from learning or attentional deficits. Currently, her research interests include relational and analogical reasoning, social cognition, stress-induced reasoning in the workplace, and improving executive function skills in cases of mild-to-moderate TBI.


Graduate Students

Zhengsi Chang

Zhengsi Chang
PhD Student — Psychological Sciences Program — UT Dallas
Email: zxc160430@utdallas.edu

Zhengsi Chang is a psychological sciences doctoral student in Dr. Daniel Krawczyk’s lab. She is currently exploring the possibility of incorporating technologies (e.g., serious games, virtual reality) into research to study human reasoning and the impact of Traumatic Brain Injury on daily functioning. Prior to joining the Center for Brain Health, she received a Bachelor of Science in biological sciences from China Agriculture University and a master degree in education from The University of Texas at Arlington.


Mehmet Gunal

Mehmet Gunal
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.


Michael Lundie

Michael Lundie
PhD Student — Cognition and Neuroscience Program — UT Dallas
Email: mjl170130@utdallas.edu

Michael Lundie started his academic career at Southern Methodist University, where he received a BA degree in philosophy with a minor in history. Shortly thereafter, he completed an MA in neurophilosophy at Georgia State University, where he engaged in interdisciplinary work on cognitive architecture and domain-general cognition.

Now a first-year PhD student in the cognition and neuroscience program, Michael works in Dr. Krawczyk’s Reasoning Lab at the Center for Brainhealth. His current research interests include using neuroimaging techniques, such as fMRI, to investigate the neural correlates of relational and analogical reasoning, the effects of biases (e.g., the Framing Effect) on judgment and decision-making, and the impact of traumatic brain injury on executive function.


Linda Nguyen

Linda Nguyen
PhD Student — Cognition and Neuroscience Program — UT Dallas
Email: ltn102020@utdallas.edu

Linda is a second-year PhD student in the cognition and neuroscience program. She is interested in social neuroscience, specifically the intersection of neuroscience, psychology, and genetics and how it informs implicit and explicit behavior and personality. She is also interested in the role of culture in behavior and personality. To study the intersection of these areas, she uses a variety of techniques including functional magnetic resonance imaging, implicit and explicit behavioral measures, and multivariate statistics. She earned her master’s degree in applied cognition and neuroscience at UT Dallas, and her bachelor’s degree in neuroscience with a minor in journalism at Baylor University.


Jelena Rakic

Jelena Rakic
PhD Student — Cognition and Neuroscience Program — UT Dallas
Email: j.rakic@utdallas.edu

Prior to joining Dr. Krawczyk’s lab, Jelena received her bachelor of arts in political science and psychology from The University of Texas at Arlington. As a research coordinator in Dr. Krawczyk’s lab, her responsibilities include neuropsychological testing, MRI scanning, and fMRI data analyses. In 2017, she graduated with a master of science in applied cognition and neuroscience from The University of Texas at Dallas. Currently, she is pursuing a PhD in cognition and neuroscience. Her research interests include traumatic brain injury, reasoning, social cognition, neural networks, emotion, and hormones.
