Dr. Ozioma Okonkwo is a tenured Professor of Medicine at the University of Wisconsin-Madison. His research focuses on clarifying how alterations in the brain and other biomolecules place some cognitively normal individuals on a trajectory that culminates in Alzheimer’s disease dementia. In this context, Dr. Okonkwo is particularly interested in discovering new knowledge concerning the modulation of the link between brain changes and cognitive decline by both modifiable and non-modifiable factors. Overlaid on this research agenda are investigations of health accessibility, and how such accessibility exacerbates or ameliorates the impact of biomarkers on clinical phenotypes.
