Research Interests

Maria’s thesis work has focused on the development and application of a machine-learning based brain age algorithm in various neurodegenerative conditions including Alzheimer’s disease,  late-life anxiety, and depression. Her other work has also investigated the impacts of various modifiable risk factors, including obesity and hypertension on neuroinflammation, as well as disease states including subjective cognitive decline, chronic pain, and anxiety disorders.
