Research Interests

Dr. Wiley's research concentrates on the pathogenesis of neurodegenerative diseases and in particular on viral and age induced nervous system diseases. Viruses damage the nervous system either by direct infection of neural cells or by secondary effects of an immune response. In recent years his studies have focused on central nervous system RNA virus infections (e.g. influenza, arboviruses and retroviral) and have pioneered the use of molecular and imaging techniques to quantitatively assess viral burden. This same technology is now being applied to quantify neurological damage and the immune / neuroinflammatory response with specific attention focused on disruption of the extracellular matrix and how this leads to synaptic damage. Dr. Wiiley is not currently taking on graduate students
