Dr. Emmenegger specializes in analyzing and predicting the deterioration of civil infrastructure from the perspective of structural engineering, corrosion engineering, and material science. He has researched and developed novel products/services to detect degradation of reinforced concrete bridges. He performs these technical investigations using a multi-disciplinary approach that also considers implications within business (marketing, supply chain, venture capital) and law (construction and intellectual property).

Prior to joining Exponent, Dr. Emmenegger was a graduate research assistant at the Georgia Institute of Technology (Georgia Tech), where he earned his Ph.D. with a construction infrastructure systems engineering specialization. He has been sponsored through projects from the Georgia Department of Transportation and National Cooperative Highway Research Board IDEA Program. His primary research investigated and developed best practices for improved longevity of reinforced concrete bridge decks through contractual incentives. Through this work, he was able to develop a sample contractual framework for improved bridge deck reliability and construction. This framework is uniquely supported by service life modeling based on historical data from in-service bridges. Prior to Dr. Emmenegger’s focus on construction infrastructure systems at Georgia Tech, he specialized in structural engineering at the University of South Florida.

Complementary to work at his primary academic institution, Dr. Emmenegger conducted research at the French Institute of Science and Technology for Transport, Development, and Networks in collaboration with faculty from Ecole des Ponts Paris Tech. While at that institution, he developed a novel structural life prediction model for reinforced concrete bridge decks which predicts degradation from construction throughout its service life. Dr. Emmenegger also has product development experience gained as a graduate research assistant at the University of South Florida. Here, he scaled-up and developed a rugged corrosion detection probe from laboratory scale to a field capable prototype. He was part of a team that successfully demonstrated the function of the new probe on portions of the old Sunshine Skyway bridge in Tampa, Florida.
