Resilient, Sustainable and Smart Ballasted Railway Track

Dr. Yunlong Guo is a Marie Skłodowska-Curie Research Fellow at the University of Birmingham, United Kingdom. He earned his PhD in Civil Engineering from Delft University of Technology. His research specializes in railway geotechnics and railway structure monitoring, employing advanced methodologies such as digital twins and machine learning.Dr. Guoqing Jing is a Professor at the Highway and Railway Engineering Department at Beijing Jiaotong University, China. He received his PhD in Civil Engineering from INSA de Rennes, France. Previously, he served as the Vice Director of the State Key Laboratory of Waterproof Materials in China and as a Guest Professor at UMP, Malaysia. Professor Jing’s current research focuses on ballasted track engineering, with an emphasis on recycled and composite materials. His work extensively utilizes numerical methods such as the discrete element method.
