Venkatagiri Krishnamurthy

Dr. Venkatagiri Krishnamurthy is a translational neuroimaging researcher advancing how vascular and neural mechanisms drive functional recovery after stroke, including language and broader cognitive outcomes; he develops vascular‑informed MRI biomarkers—multi‑PLD CBF and CVR transfer‑function measures (gain/phase)—to characterize lesion, perilesional, and collateral physiology and improve prognostic accuracy for individualized rehabilitation. He also leverages multi‑echo resting‑state fMRI (ME‑rsfMRI) to map echo‑specific patterns of network reorganization that differentiate responders from non‑responders to standard care, offering mechanistic insight that complements biomarker‑based stratification. His program integrates Bayesian tensor‑based longitudinal modeling to quantify treatment‑related neuroplasticity and concurrent tDCS–fMRI to reveal how neuromodulation shapes large‑scale networks in chronic stroke and aphasia. Extending beyond stroke, his multimodal biomarker research links cerebral blood flow, neurometabolites, and cardiorespiratory fitness to cognitive aging, delivering imaging‑based frameworks that enhance prognosis and guide precision rehabilitation for persons recovering from stroke‑related communication, cognitive, and functional deficits.
