President and Principal Engineer
Hasan Ozer, Ph.D., M.ASCE
Director of Infrastructure and Principal Engineer
Imad Al-Qadi is an internationally renowned expert in pavements and sustainability. He has served as principal investigator on more than 100 projects sponsored by various federal, state, and international agencies and industry and has managed more than 200 projects. He has also consulted for more than 50 agencies and companies. He served as the Via Professor at Virginia Tech and Founder Professor of Engineering and Director of the Advanced Transportation Research and Engineering Laboratory (ATREL) and the Illinois Center for Transportation (ICT) at the University of Illinois at Urbana-Champaign. Dr. Al-Qadi holds a Ph.D. (1990) from Penn State and is a registered professional engineer. He is an elected Distinguished Member of the American Society of Civil Engineers (ASCE), honorary member of the Societa Italiana Infrastrutture Viarie, honorary professor at several international universities and served on the board of numerous international conferences. He has received numerous awards, some of which is the only pavement engineer to earn. He is the Past President of the Board of Governors of the ASCE Transportation and Development Institute and served as a committee chair on various professional and technical committees and has organized and chaired more than 20 international conferences. As a leader in his field, he has contributed to the pavements field through many developments and authored/coauthored more than 600 publications and delivered more than 550 national/international presentations.
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.

Rebekah Yang, E.I.T.
Director of Technology and Principal Engineer
Yanfeng Ouyang brings in many years of technical experience in transportation systems analysis, operations management, large-scale optimization, and data analytics. Since receiving his Ph.D. from the University of California at Berkeley in 2005, Dr. Ouyang has served as a principal investigator or co-principal investigator of over 50 research projects, with over $13 million of total funding, from various sponsors such as the U.S. National Science Foundation, U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, U.S. Department of Transportation, Illinois Department of Transportation, Illinois Toll Highway Authorities, and the private sector (e.g., ADM and CSX). His research outcomes have been successfully transferred to field practice, leading to various prestigious awards such as a 2014 High Impact Project Award from the Illinois DOT, a 2013 Chairman’s Award of Excellence from CSX Inc., and a 2015 Walter L. Huber Civil Engineering Research Prize from the American Society of Civil Engineers. He is an active member and officer of professional societies such as the Transportation Research Board (TRB), the Institute for Operations Research and the Management Science (INFORMS), and the American Society of Civil Engineers (ASCE). He has authored/coauthored well over 100 technical publications and delivered more than 250 national/international presentations. He is also a Department/Area/Associate Editor of multiple top academic journals.
Rebekah Yang is a Ph.D. student at the University of Illinois at Urbana-Champaign (UIUC) and a graduate researcher at the Illinois Center for Transportation (ICT). Ms. Yang holds a B.S. (2012) from Swarthmore College in engineering and a M.S. (2014) from University of Illinois at Urbana-Champaign in civil engineering. Ms. Yang’s research and interests focus primarily on transportation sustainability. Her master’s thesis, “Development of a Life Cycle Assessment Tool for Pavement with Regional Life Cycle Inventory Models for Asphalt Binder Production,” along with other published works are largely focused on roadway sustainability and the use of life-cycle assessment. Ms. Yang is the 2015-2016 president of the ASCE Transportation and Development Institute Graduate Student Chapter at UIUC. She was awarded the Helene M. Overly Graduate Scholarship from the WTS (Women in Transportation Seminar) Chicago Chapter in 2014 and received the Airport Cooperative Research Program Graduate Research Award and a Dwight Eisenhower Graduate Fellowship to conduct research related to airport and highway pavement sustainability during the 2015–2016 term.
