Katja Kanninen, PhD, is a professor of cellular neurobiology at the A.I. Virtanen Institute for Molecular Sciences at University of Eastern Finland, Finland. Her research is focused on the cellular and molecular mechanisms of Alzheimer’s disease. By using human cell cultures and animal models for the research, she investigates how lifestyle and environmental factors affect brain health and are implicated in neurodegeneration. Her research strives to understand how airborne agents such as air pollutants or viruses affect the brain, and to explain the cellular and molecular pathways involved.
