Director of Infrastructure and Principal Engineer
Tel: +1-773-888-1934; Email: ozer@testsustainability.com

Hasan Ozer’s research and teaching interests are in the area of infrastructure materials, structural performance modeling of pavements, and transportation sustainability. His research is primarily concentrated in the areas of computational fracture mechanics, numerical modeling of pavement response, sustainable pavement systems, use of recycled materials in pavements, rheological and mechanical characterization of highly polymerized asphalt binder, and wireless sensor networks for monitoring infrastructure’s health. Dr. Ozer currently serves as principal or co-principal investigator of several Illinois Department of Transportation (IDOT) and Federal Highway Administration (FHWA) sponsored studies on recycled material characterization and development of sustainable pavement systems.  Dr. Ozer is currently involved in nationwide and several Illinois based research projects on the development and promotion of transportation sustainability. Sustainability has emerged as a critical consideration in the transportation sector as well as in the construction industry worldwide. An objective sustainability rating system and life-cycle assessment tool is under development for the use of Illinois State Highway Agencies (SHAs). A critical outcome of these programs is to increase the awareness, visibility, and the body of knowledge of sustainability considerations in the design, construction, maintenance, and rehabilitation of pavement systems. Dr. Ozer’s research scope on sustainability encompasses development of guidelines to improve sustainable practices, sustainability assessment of highway infrastructure, and alternative materials used in asphalt mixture production and aggregates production.
