My overarching research interest aims at investigating data related to human, buildings, and urban infrastructures for smart buildings and cities. Methodologically, this includes data analytics (e.g., machine learning, visual analytics, signal processing) as well as data acquisitions and management (e.g., sensors, actuators, processors, networks). I primarily investigated two topics, 1) Human Building Interaction, and 2) Building to Grid integration.
