Research Interests:

The Thomas laboratory is focused on understanding the molecular mechanisms involved in the pathogenesis of both age-related and childhood neurodegenerative disorders, with special emphasis on mitochondrial dysfunction and stress signaling cascades involving oxidative stress and neuroinflammation. The overall goal is to utilize this mechanistic knowledge to develop tangible neuroprotective therapies.
