Colin Combs, Chester Fritz Distinguished Professor of Biomedical Sciences, and his postdoc, Harpreet Kaur. They have two lines of research going, both targeting Alzheimer's and dementia. One uses dietary interventions, the other focuses on finding a drug. Goals of both are to delay/cure the problems, one of which is neuroinflammation, or inflammation in the neurons/brain.
