Members of the team at the Laboratory for Intelligent Systems and Technologies (LIST) work at the boundary between traditional civil engineering and related engineering disciplines (such as electrical engineering, computing science, and material science) to convert traditional civil infrastructure systems into more intelligent and reactive systems through the integration of sensing, computing, and actuation technologies. The conversion of society’s infrastructure systems into cyber-physcial systems (CPS) greatly enhance their performance while rendering them more resilient against natural and man-made hazards. Infrastructure whose health is closely monitored also have lower life-cycle costs and significantly longer services lives over which their initial carbon footprint is amortized.
Currently, students and faculty are focusing their research efforts on the creation of new sensors including those fabricated using microelectromechanical systems (MEMS) and nanotechnology. LIST researchers are also at the forefront of the development of “intelligent” wireless sensors that collect sensor data from bridges, buildings, pipelines, among other infrastructure systems. Data processing architectures are being explored to process data within wireless sensor networks to autonomously convert data into the information direly sought by system end-users for their decision making. The team is also advancing a comprehensive “data to decision” cyberenvironment that provides a scalable platform for the storage of sensor data and system meta-data. Within the cyberenvironment, an extensive library of data interrogation algorithms based on physics-based and data-driven methods are used to assess the performance and health of monitored infrastructure systems. Finally, the LIST team is advancing actuation technologies that control the response of infrastructure systems to extreme loads and that reconfigure individual and interdependent infrastructure systems to enhance resiliency against hazards.

Rackham School of Graduate Studies.
