About Us
ABOUT US
The BRAIN (BYU Research and Imaging in Neuropsychology) Lab, led by Dr. Tricia Merkley, investigates how traumatic brain injury affects brain structure and neurobehavioral functioning during recovery. We use advanced neuroimaging techniques (including structural MRI) and neuropsychological assessment to study brain-behavior relationships across the lifespan. We use tools such as Freesurfer for cortical reconstruction and brain volume analysis, along with lesion mapping and connectivity approaches to better understand outcomes in various TBI populations (e.g., pediatric/adult, intimate partner violence, military, sports), with severity of injury ranging from mild to severe. Our goal is to identify imaging biomarkers and cognitive and behavioral indicators that can help monitor recovery over time and guide treatment, in addition to lifestyle and/or treatment factors to improve long-term outcomes for individuals affected by brain trauma.
LAB CULTURE
The BRAIN Lab values collaboration, scientific rigor, and intellectual curiosity. We provide an environment where graduate and undergraduate students work together to explore meaningful questions in clinical neuroscience. Weekly lab meetings create space for discussion, feedback, hands-on learning, and problem solving. We support each other’s growth through mentorship, shared responsibility, and a commitment to producing research that is both methodologically strong and clinically relevant.
LAB EXPECTATIONS
Undergraduate Students
Undergraduates in the BRAIN Lab assist with ongoing studies related to neuroimaging and brain injury. Typical responsibilities include learning research methods, data quality review and processing, image analysis using neuroimaging tools and software, and literature review. Students are especially encouraged to apply if they are interested in clinical neuropsychology, medicine, neuroscience, or related fields. A strong background in computer programming, neuroimaging analysis, neuroanatomy, and statistical analysis is highly preferred. Ideal candidates are motivated, dependable, proactive, and curious about brain science. They also have personal integrity and are committed to contributing to the existing knowledge base in the field, with the intent to further practical clinical application. A minimum commitment of 10 hours per week for at least one year is required to complete lab training and contribute to ongoing projects. This hands-on experience provides valuable preparation for graduate school, medical school, and research-oriented careers.
Graduate Students
Graduate students in the BRAIN Lab lead research projects from design to publication. Dr. Merkley provides individualized mentorship that supports both independent development and collaborative contribution. Strong applicants are pursuing a career in clinical neuropsychology and bring experience in neuroimaging, neuropsychological assessment, and/or clinical research. Graduate projects often involve large datasets, multi-site collaborations, and advanced analysis techniques related to brain-behavior relationships. Students are encouraged to shape their work around both lab priorities and their own related scientific interests.
