Dr. Vikram S. Chib is an Associate Professor of Biomedical Engineering at Johns Hopkins University and a research scientist at the Kennedy Krieger Institute. His work explores the neural basis of decision-making, cognitive motivation, and fatigue using brain-imaging tools such as fMRI. Dr. Chib leads pioneering studies into how the brain balances the perceived cost of mental effort against the potential benefits—insights that have crucial implications for conditions like depression and PTSD, where cognitive exhaustion is common.
