Dr. Xinji Ji is a specialist in wearable technology and player tracking, with a professional focus on how GPS and athlete-monitoring systems can be translated into practical decision-making in football environments.
Academically, she studied at KU Leuven, building a foundation that supports her applied work at the intersection of sport science, technology, and performance operations. Her career pathway has been shaped by roles in leading industry organisations, including experience with Catapult Sports, where GPS and tracking workflows are central to performance monitoring and load-management processes across elite sport. She has also worked with BodyPlus Technology, further strengthening her expertise in athlete data capture, wearable ecosystems, and the interpretation of monitoring outputs in real-world settings.
Across these roles, Dr. Ji has developed a clear applied identity as a GPS expert, supporting practitioners to move beyond raw outputs and into actionable insights. Her core strength sits in player tracking data applications in soccer—connecting external load metrics to training design, microcycle planning, athlete readiness, and return-to-play progression. This includes understanding how to operationalise key variables (e.g., distance bands, high-speed running, accelerations/decelerations, positional demands) while respecting the practical realities of coaching language, session objectives, and individual player context.
Fluent in English and Chinese, Dr. Ji is well positioned to contribute to global high-performance environments and education settings, helping staff and organisations build stronger data literacy around wearable technology—ensuring monitoring systems drive better conversations, clearer planning, and more confident performance decisions.
