A voxel-level approach to brain age prediction: A quantitative method to assess regional brain aging
… biomarker to study the correlation between brain aging and neurological disorders. However, brain aging is a regional phenomenon, a facet that remains relatively under-explored within the realm of brain age prediction research using machine learning methods. Voxel-level predictions can provide …

Fully Hyperbolic Graph Convolutional Neural Networks for Age Prediction with Multi-Modal Brain Data
… networks holds great promise in understanding aging trajectories and revealing aberrant patterns of neurodegenerative disorders, such as Alzheimer’s disease. In this study, we utilize a Fully Hyperbolic Neural Network (FHNN) to embed functional brain connectivity graphs, derived from …

Identifying Cognitive Profiles and Determinants of Cognitive Superaging Among Older Adults
Cognitive aging among older adults is heterogeneous and does not follow a single trajectory. This study used a person-centered approach to identify cognitive profiles, specifically cognitive superagers, among United States adults aged 75 and older and to quantify transitions between cognitive …

MicroRNA Gene Expression States Underlying Individual Variation in Aging and Lifespan in Isogenic C. elegans
… identical individuals to diverge on different aging trajectories. This dissertation aims most principally to prove the existence of such regulatory genes (e.g., “biomarkers of lifespan”) and characterize the resulting gene expression states that define long- and short-lived individuals in C. …
