Geyang Song is a skilled ground engineer with expertise in sensor development and a deep understanding of fundamental soil mechanics and constitutive modelling. His experience in these areas was enhanced during his MSc studies at Imperial College London and through extensive research during his PhD and postdoctoral roles. ​ Geyang's research journey began during his PhD at the University of Nottingham (2016-2019), where he conducted a physical and numerical study on the use of protective structures to reduce tunnelling-induced damage to piled structures. To do this, he developed a novel mechanical model tunnel to simulate tunnel volume loss, led the development of coupled centrifuge and numerical modelling techniques, and employed advanced numerical constitutive models to simulate soil-structure interactions. A significant aspect of his work involved using fibre Bragg grating sensors for geotechnical centrifuge testing, which was the first step into sensor technology. ​ In his subsequent role as a Postdoctoral researcher at the University of Oxford (2021-2023), Geyang furthered his sensor development prowess by developing and commercialising a novel six-degree-of-freedom force sensor. This multi-faceted project involved creating a digital twin of the sensor body, developing a machine learning algorithm for calibrating the force sensor, and creating a minimum viable product used for a field monitoring project. As a dedicated researcher and scholar, Geyang has contributed to the publication of ten peer-reviewed international journal papers and six high-quality conference papers, reflecting his commitment to knowledge-sharing and innovation in his field. Geyang continues to explore and innovate, driven by a passion for advancing sensor technology in ground engineering.
