I am a Ph.D. student under the supervision of Prof. Tobias Oechtering and the co-supervision of Prof. Magnus Jansson. I obtained my Master's degree in Information and Network Engineering in 2024 from KTH, Sweden, and my Bachelor's degree in Information Engineering in 2022 from Southeast University, China.

My research focuses on trustworthy digital twins for smart buildings. I am interested in privacy and fairness, signal processing, pattern recognition and machine learning.

Barricelli et al. [1] provide a comprehensive definition of digital twin. A digital twin is a living, intelligent and evolving model, being the virtual counterpart of a physical entity or process. It follows the lifecycle of its physical twin to monitor, control, and optimize its processes and functions. It continuously predicts future statuses (e.g., defects, damages, failures), and allows simulating and testing novel configurations, in order to preventively apply maintenance operations.
