Andrew Petkus is an Associate Professor of Clinical Neurology with research focusing on environmental impacts on brain health, cognitive aging, and neurodegenerative disorders.

Research examines air pollution effects on cognitive decline, dementia risk factors, and neuropathology in aging populations. Studies utilize longitudinal data to identify environmental and genetic contributors to neurodegeneration.

Publications investigate particulate matter exposure, cognitive trajectories, and brain structure changes in elderly populations.
