Biography


Tengjiao Jiang is currently a Postdoctoral Fellow in the Structural Dynamics group at the Department of Structural Engineering, Norwegian University of Science and Technology, NTNU.  His main task is to focus on the dynamic properties of railway bridges and catenary systems in service by photogrammetric measurements.

His research aims to adapt photogrammetric measurements to issues and applications in damage detection, model updating, validation and verification to improve maintenance and operation of infrastructure.
