David  Kosnik

Senior Engineer, Structural Evaluation

Dr. Kosnik draws from his dual background in civil and computer engineering to develop innovative performance monitoring and evaluation solutions for in-service infrastructure. His experience includes development of long-term, continuous remote monitoring deployments on highway and rail bridges, movable structures, tunnels, excavations, structures subject to ground vibration, and infrastructure vulnerable to hydraulic and geo-hazards such as scour, sinkholes, and subsidence.

Dr. Kosnik's monitoring strategies support critical infrastructure management decisions through quantitative evaluation of retrofits and life extension efforts, determination of vibration limits, characterization of damage progression, and early warning of possible disruption. Acoustic emission monitoring provides insight for management of fatigue-prone bridge details and anomalous noises on movable structures. Dr. Kosnik has completed the FHWA-NHI training for safety inspection of in-service bridges and fracture-critical inspection of steel bridges.

Prior to joining CTLGroup, Dr. Kosnik was a researcher at the Northwestern University Infrastructure Technology Institute, an applied research center focused on sensing and monitoring for in-service transportation infrastructure. He has written several peer-reviewed journal and conference proceedings articles on structural health monitoring, acoustic emission testing, and computing in civil engineering, and has made many presentations at national and international conferences.
