Research Interests

The regulation and role of brain lipid metabolism in neurodegenerative diseases and neuropsychiatric disorders.


Research Synopsis

The overall goal of my research program is to identify the mechanisms that regulate brain lipid metabolism (signaling) and to identify the role of brain lipid metabolism in the pathogenesis of neurodegenerative diseases and neuropsychiatric disorders. We are currently taking a kinetic and biochemical approach to studying the mechanisms by which dietary polyunsaturated fatty acids regulate the metabolism of arachidonic and docosahexaenoic acids within brain phospholipids. We are also investigating the role of dietary polyunsaturated fatty acids in rodent models of neuroinflammation and Alzheimer's disease.
