Dr. Vivek Tiwari’s research group  is dedicated to uncovering clinically relevant  structural, metabolic, and epigenetic events associated with brain  health and disorders, with a particular focus on  aging and aging-associated brain disorders and  Brain tumors. His research group aims to understand the molecular and neurobiological mechanisms underlying neurodegeneration, cognitive decline, and tumor progression, bridging fundamental and clinical neuroscience. 

The group employs a multidisciplinary approach, integrating advanced neuroimaging techniques (MRI, spectroscopy, and fiber tractography), metabolic imaging, genetic and epigenetic analyses, and artificial intelligence-driven modeling. A key focus is developing novel metabolic models to generate in vivo metabolic maps of the aging brain and tumor microenvironment, providing insights into structural and functional heterogeneity in brain disorders.
