Dr. Gagan Wig’s research uses functional imaging to understand the organization of human brain networks, specifically focused on understanding healthy and pathological aging. Dr. Wig’s recent research helped develop a theoretical and methodological framework for analyzing brain connectivity and brain networks. His work has begun to reveal how brain networks differ across the adult lifespan, and how individual differences in brain network organization relate to cognitive ability. Dr. Wig’s research also involves the use of brain imaging and non-invasive brain stimulation to understand memory and attention in humans. Dr. Wig is a member of the Memory Disorders Research Society and research from his lab has been featured in numerous scientific and public news reviews and articles. Dr. Wig earned his bachelor’s degree from the University of British Columbia and his Ph.D. from Dartmouth College, followed by post-doctoral fellowships at Harvard University and Washington University in St. Louis with the Human Connectome Project.
