His teaching, research and service focuses on structural engineering and construction materials. Dr. Weldon graduated with his Masters and Ph.D. degrees from the University of Notre Dame. His research includes development of Ultra-High Performance Concrete (UHPC) using local materials; resilient earthen construction; load rating of bridges without plans; and modeling, design and experimental evaluation of structural elements under extreme loading. Dr. Weldon is a regular lecturer in the bridge inspection training courses and the quality concrete school. Dr. Weldon is the CBBG senior investigator (with Dr. Bandini) of a project that aims to increase the resilience of adobe construction under extreme lateral loading and weather hazards.
