Martin Sliwinski

Martin Sliwinski, Ph.D., is the Gregory H. Wolf Professor of Aging Studies and Professor of Human Development and Family Studies at Pennsylvania State University. He serves as Director of the Center for Healthy Aging. His research focuses on cognitive aging mechanisms, with emphasis on psychosocial and biological factors influencing cognitive health in mid-to-late life. Dr. Sliwinski develops and applies innovative digital methods for real-time cognitive assessment using smartphone-based technologies.

Key research themes include: loneliness-cognition interactions, inflammation's role in cognitive decline, dietary interventions for neuroprotection, and epigenetic biomarkers of aging. He leads large-scale longitudinal studies involving ambulatory physiological monitoring and ecological momentary assessment. His work bridges clinical neuroscience with public health policy through translational studies on dementia prevention strategies.

Notable contributions include pioneering high-frequency cognitive assessment protocols using mobile devices, which have advanced understanding of within-person cognitive variability. He collaborates with multidisciplinary teams to integrate metabolomics, neuroimaging, and sensor data for comprehensive aging research. Dr. Sliwinski's lab website (http://sliwinskilab.weebly.com) showcases ongoing studies in cognitive aging mechanisms and intervention development.

Current projects explore: (1) digital phenotyping of preclinical Alzheimer's disease using smartphone data (2) neighborhood environment impacts on cognitive trajectories (3) biomarker-cognition relationships in type 1 diabetes patients (4) stress-cognition associations across gender and race. His work has been funded by NIH grants focusing on technology-driven aging research and health disparities.
