Dr. Wig is an associate professor in the Center for Vital Longevity and School of Behavioral and Brain Sciences at The University of Texas at Dallas, and in the Department of Psychiatry at The University of Texas Southwestern Medical Center. Dr. Wig earned his bachelor’s degree from the University of British Columbia and his PhD from Dartmouth College, followed by post-doctoral fellowships at Harvard University and Washington University in St. Louis with the Human Connectome Project.

Dr. Wig’s research uses functional and structural imaging to understand the organization of human brain networks, specifically focused on understanding how brain networks change across the adult lifespan in both health and disease. Dr. Wig’s research has helped to develop a theoretical and methodological framework for analyzing patterns of brain connectivity and brain networks. This work is revealing how brain networks change across the adult lifespan, and how individual differences in these network changes relate to age-related cognitive decline. Dr. Wig’s recent research is examining how changes in aspects of an individual’s socio-economic environment and lifestyle interact with their brain network organization to predict their resilience and vulnerability to cognitive decline. Dr. Wig’s research is presently supported by grants from the National Institute of Aging (NIA) and the James S. McDonnell Foundation (JSMF).
