Working to understand: Alzheimer’s disease, Fragile X mental retardation syndrome and other CNS disorders which are associated with abnormal lipid regulations
Scientific Focus: My long-term goal is i) to define the molecular mechanism underlying the physiological regulation of endocannabinoids and other bioactive lipids, and ii) to determine their relevance to the pathogenesis of neurological diseases.
