Research Strength: Neurobiology of Disease

My lab focuses on understanding the physiopathology of, and developing treatments for neurological disorders, in particular Parkinson's disease. Our translational projects are intensely collaborative and multidisciplinary. We are working toward developing better animal models of neurodegenerative disorders and non invasive, sensitive methods of evaluation. We are studying the effects of stem cells, embryonic or progenitors in the nonhuman primate brain. Ex vivo and in vivo gene transfer approaches are used to deliver therapeutic molecules in the brain such as glial derived neurotrophic factor (GDNF) on existing dopaminergic neurons in the brains of parkinsonian animal models. The program also addresses the clinical translation of small molecules targeting antioxidative, anti-inflammatory and antiapoptotic pathways for treatment of neurodegenerative disorders.
