Saul Villeda is an Associate Professor in the Department of Anatomy at the University of California San Francisco School of Medicine and holds the title of Endowed Professor of Biomedical Sciences. He also serves as Associate Director of the Bakar Aging Research Institute. He earned a B.S. degree in Physiological Sciences from the University of California, Los Angeles in 2004 and a Ph.D. in Neuroscience from Stanford University in 2011. Villeda began his independent career at UCSF as a Sandler Faculty Fellow before advancing to his current faculty position.
His research program investigates the cellular and molecular mechanisms underlying brain aging and rejuvenation, with a focus on how systemic changes in blood influence regenerative capacity, synaptic plasticity, neuroinflammation, and vascular integrity in the adult hippocampus. Key findings from his laboratory demonstrate that interventions such as heterochronic parabiosis, administration of young blood plasma, and exposure to exercise-induced blood factors can partially reverse age-related cognitive and regenerative impairments. This work has implications for counteracting dementia-related neurodegenerative diseases. Villeda has received several honors, including the 2023 Byers Award in Basic Science, the 2022 McKnight Brain Research Foundation Innovator Award in Cognitive Aging and Memory Loss, the 2015 Glenn Award for Research on the Biological Mechanisms of Aging, and the 2012 NIH Director’s Early Independence Award. He is the author of numerous peer-reviewed publications on these topics.
