Tom Van Dam
Dr. Van Dam has 35 years of experience in pavement design and evaluation, concrete, materials assessment, and sustainability. He has managed large projects for the FHWA, various state departments of transportation, and the Innovative Pavement Research Foundation to analyze the effects of concrete properties and durability on pavement performance, and he has published numerous articles and papers.
Dr. Van Dam graduated from the University of Illinois Urbana-Champaign with a bachelor of science and master of science in Civil Engineering, and a doctorate in Philosophy. He’s a member of several national associations, including the American Concrete Institute, the American Society of Civil Engineers, the Transportation Research Board, and the International Society of Concrete Pavements. His areas of expertise include sustainable civil engineering infrastructure, airport and highway pavement performance, durability, and training.
James Bogdan is the vice-president of Sustainability Initiatives for the National Ready Mixed Concrete Association. Based in the greater Pittsburgh area, he helps NRMCA members meet evolving sustainability-related requirements in building construction standards, sustainability initiatives including product sustainability and transparency, responsible sourcing, and other environmental, social, and governance (ESG) practices. James also assists with developing strategies that will support concrete’s position within standards development and manages a variety of education and certification programs for the association.

Tyler Ley, PhD, PE, FACI, has more than 19 years of experience in the fields of cement-based materials. He has worked as an engineer with a design consultant, construction contractor, and government agency in addition to being a professor. Tyler’s practical experience, blended with his technical expertise, has elevated both his teaching and research. His research focuses on the durability and construction of cement-based materials. As a result, he has developed national and state specifications, test methods and policy changes.
Tyler is a fellow of the American Concrete Institute (ACI) and the American Ceramic Society (ACerS) and has received several awards including the National Science Foundation (NSF) Career Award, the ACI Faculty Achievement Award and the Regents Research Award from Oklahoma State University. He also hosts a popular YouTube channel about concrete.
David Shepherd, AIA, is the Midwest region manager for CRSI, promoting the benefits of reinforced concrete to design professionals and other key stakeholders. He has 40 years of experience working across the spectrum of the design and construction industry. Before working at CRSI, David was PCA’s director of sustainable development for 14 years. Earlier this year, he was awarded the American Concrete Institute’s Sustainability Award "for his collaborative outreach in promoting concrete sustainability."
Jeff Groom, PE, is the senior principal engineer for CTL Thompson, Inc. With over 35 years of experience, Jeff specializes in concrete consulting and quality control testing of construction materials including concrete, aggregates, mortar, grout, and masonry units. His experience includes concrete mix proportioning (normal weight, light weight, heavy weight, and roller-compacted concrete) for horizontal and vertical construction applications. A frequent speaker, published author, and expert witness, Jeff has consulted around the world on projects involving concrete damage and construction defects. He is an active member of American Concrete institute, American Society of Civil Engineers and ASTM Committee C9 on Concrete Aggregates.
Jeff received his BS and MS degrees in Civil Engineering from the University of Wyoming and is a registered Professional Engineer in Colorado, Wyoming, Montana, Nebraska, Louisiana, and Guam.
John S. Lawler
Since joining WJE in 2001, John Lawler has performed field, laboratory, and analytical investigations related to the construction and durability of a wide range of structures. His areas of specialization include concrete structure assessment, nondestructive testing techniques, corrosion testing, and corrosion service life modeling for new and existing structures in severe environments. Dr. Lawler has consulted on materials selection and design for new structures, with a focus on durability. He has led research programs investigating materials performance in the field and the laboratory. This has included studies of corrosion-resistant reinforcing steels, prestressing strand, and high-performance concrete optimized for durability.
Vincent J. Kania
Vincent Kania is an associate structural engineer with Wiss, Janney, Elstner Associates, Inc., and has structural engineering degrees from the University of Illinois at Urbana-Champaign and the University of California, Berkeley. He has experience in the investigation, analysis, repair, and retrofit of reinforced, prestressed, and post-tensioned concrete. Mr. Kania also has laboratory and field experience in full-scale structural load testing, as well as experience in new design and load ratings for highway and railroad bridges. He recently assisted with the shear testing and structural analysis of fifteen full-size UHPC girders for the PCI-UHPC research project. Mr. Kania is a member of the American Concrete Institute subcommittee ACI 239C on the structural design of UHPC.
