Hasan Ozer, Ph.D., M.ASCE
Director of Infrastructure and Principal Engineer
Imad Al-Qadi, Ph.D., P.E., Dist.M.ASCE is the Founding President of TEST, Inc. He is also the Bliss Professor of Engineering at the University of Illinois at Urbana-Champaign. Additionally, he serves as the Director of the Advanced Transportation Research and Engineering Laboratory (ATREL), the founding Director of the Illinois Center for Transportation (ICT), and the founding Director of the Smart Transportation Infrastructure Initiative. Prior to that, he was the Charles E. Via, Jr. Professor at Virginia Tech. A registered professional engineer, Professor Al-Qadi has authored/coauthored approximately 600 publications and delivered more than 600 presentations including numerous keynote lectures. He has led more than 120 projects to completion; in addition, he has managed more than 240 projects as the ICT director since 2006. He is the past president of the ASCE T&DI Board of Governors and the Editor-in-Chief of the International Journal of Pavement Engineering. Professor Al-Qadi has received numerous prestigious national and international honors and awards including the NSF Young Investigator Award, the quadrennial IGS Award, the ASCE James Laurel Prize, the ARTBA Steinberg Award, the ASCE Turner Award, and the French Limoges Medal. He is a Chapter Honorary Member of Chi Epsilon at the University of Illinois, an Honorary Member of the Societa Italiana Infrastructure Viarie, Emeritus Member of TRB Committee AHD25 on Sealants and Fillers for Joints and Cracks, and an Honorary Professor at several universities in Europe and China. In 2010 he was elected as an ASCE Distinguished Member. Dr. Al-Qadi holds a B.S. degree from Yarmouk University and M.Eng. and Ph.D. degrees from Penn State University, all in civil engineering. His expertise is on highway and airfield pavement mechanics and evaluation, tire-pavement interaction, GPR, asphalt rheology, pavement sustainability, and forensic engineering and arbitration.
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.
Yanfeng Ouyang, Ph.D., M.ASCE
Director of Operations 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.

TEST-ME Team

Yara Hamdar, M.Eng, M.ASCE graduated from the American University of Beirut with a Masters degree in Pavement Engineering (2016). Her Masters thesis, and other research projects she worked on at the university, drew on regional challenges that pavement project stakeholders commonly face in the Middle East. Among her achievements is the development of a simplified mechanistic-empirical pavement design tool. Her practical experience includes consultancy on regional airport and highway pavement projects. She has also actively participated in the organization of regional conferences and workshops. Through research and practice, she has cultivated experience in pavement design, performance-based specifications, and sustainability.
