Research Interests

The SAGE Research Lab examines (1) various aspects of sleep, and (2) changes associated with advancing age. In terms of sleep, the lab investigates aspects of normal sleep, insomnia, and sleep apnea. We aim to learn more about how sleep impacts important aspects of life, including: mood, pain, physical activity, and cognitive functioning. The lab is interested in identifying potential biological mechanisms, such as inflammation, that may link sleep and these important outcomes. We also explore methods to improve disturbed sleep in individuals with insomnia and/or sleep apnea. In regards to age-related phenomenon, the lab’s focus is on late-life cognitive functioning. Specifically, we aim to identify and intervene on modifiable targets (like sleep) for cognitive dysfunction in older adults. In general, the research conducted in the SAGE Research Lab involves both basic and applied science, with the ultimate goal of improving the lives of older adults.
