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. My research interests include: representativeness, information-theoreticprivacy and bias of models; signal processing; pattern recognition and machine learning.

A digital twin[1] is the virtual counterpart of a physical entity or process. It is a living and evolving model that follows the lifecycle of its physical twin. It continuously predicts future states (e.g., defects, damages, failures). It allows simulating and testing novel configurations. It can monitor, control, and optimize its physical twin (e.g., management, fault detection).
