  1. $10.6 million spent. Research: Our scientists study a broad array of research models to identify the cellular basis for regeneration and aging in humans and how environmental toxins such as arsenic and PFAS impact our susceptibility to disease. Our goal is to develop new therapeutic approaches to enhance our ability to repair cellular damage and resist the degenerative changes that occur with age.In 2024, we welcomed a new faculty member Dr. Emily Spaulding, whose outstanding research on the cellular mechanisms of neurodegenerative disease has been recognized by the National Institutes of Health. We were awarded a total of $30,821,832 in multi-year federal grant funding in 2024, including renewal of the largest state-wide research and training network connecting 17 academic and research institutions in Maine.
