Research Interests:
Dr. Logan’s research focuses on mitochondrial metabolism and its effects on cognitive aging. She is particularly interested in the cell-specific alterations with age that make the aged brain more susceptible to cognitive decline during normal aging and in neurodegenerative conditions such as, Alzheimer’s disease. Astrocytes are an important cell type in the brain that have an integral role in the maintenance and modulation of neuronal health and function by supplying important trophic factors and energy substrates necessary for normal function. Dr. Logan’s work delves into the mechanisms by which oxidative stress and the decline in a tropic hormone (IGF-1) changes with age mediate astrocytic responses in the brain to influence cognitive performance.
