Fabio Valdés

Dr. Fabio Valdés is a researcher at FernUniversität in Hagen's Faculty of Mathematics and Computer Science, specializing in spatial databases and trajectory data analysis. He teaches core modules including Softwaresysteme, Databases and Security on the Internet, and Data Mining while leading advanced research in metric space indexing and pattern recognition.

His research focuses on symbolic trajectories, efficient pattern matching for time-dependent data, and metric space indexing. Key contributions include the N-tree index structure for trajectory similarity search and frameworks for spatio-textual trajectory mining. His work bridges theoretical foundations with industrial applications in aircraft tracking, wildlife monitoring, and industrial image processing systems.

Analysis of his 15 most recent publications reveals an evolution from foundational symbolic trajectory models (2013-2017) to advanced indexing structures (2020-2025). Current work integrates machine learning for neural network interpretability and energy price forecasting, maintaining strong ties to ACM SIGSPATIAL and IEEE venues while expanding into AI-driven applications.
