Stathis C. Stiros

About

Stathis C. Stiros is a prominent Greek researcher whose work sits at the intersection of geodesy, structural monitoring, and geotechnical engineering. He is best known for pioneering the use of Robotic Total Stations (RTS) and GPS technologies to measure dynamic deflections, oscillation frequencies, and structural responses of bridges and other engineering structures. His landmark 2013 study marked the first application of RTS to measure railway bridge deflections under live train loading, a contribution that has since accumulated nearly 150 citations and reshaped structural health monitoring methodology. Stiros has systematically advanced the accuracy benchmarks for geodetic instruments in dynamic settings, demonstrated through comparative GPS-RTS assessments and supervised learning algorithms designed to extract oscillation parameters from noisy sensor records. His research extends beyond bridge engineering into seismology, where he has evaluated high-frequency GPS for capturing strong-motion displacement waveforms, and into geohazards, including geodetic monitoring of slow-moving landslides. With multiple papers exceeding 50 citations and a cumulative body of work spanning over two decades, Stiros has significantly influenced how engineers and geodesists instrument, monitor, and interpret the behavior of civil infrastructure, combining rigorous field experimentation with innovative signal-processing approaches.
