Personal profile

Area of Expertise

The O’Bryant laboratory is dedicated to precision medicine in Alzheimer’s disease and other neurodegenerative diseases, including Down syndrome, Lewy Body disease, Parkinson’s disease, traumatic brain injury, and others. The fully translational lab has a Biomarker Core (Dr. Hall, Director), Clinical Core (Dr. Johnson, Director), Administrative Core (Dr. O’Bryant, Director) and Data Core (Dr. Johnson, Director). The lab also has a Neuroimaging Core (USC, Dr. Toga, Director). Dr. O’Bryant's multiple NIH grants focus on novel strategies for disease detection, screening into trials (therapeutic and prevention), and patient stratification for optimal treatment response. As part of this work, the lab has a strong focus on the impact of ethnicity/diversity on cognitive loss during the aging process and runs the one-of-a-kind Health & Aging Brain among Latino Elders (HABLE) study, which is the most comprehensive study of Mexican-American brain aging to date.
