I am a ITF-funded Postdoctoral Fellow at the Department of Computing at Hong Kong Polytechnic University (PolyU), working with Prof. Dan WANG and Prof. Chen Jason Zhang.

During my PhD study in PolyU, my research interest lies in machine learning model evaluation in Building Energy System, with hands-on experience in time series forecasting and applications in building HVAC system. I have also contributed my expertise to support AI competitions for Building E&M Facilities hosted by the Hong Kong government. My recent research centers on enhancing the “Scalability” of AI in (building) energy systems, with a focus on two following perspectives: a) Large Foundation Model and b) Model Ensemble. More details of my overall research framework can be found here.

Prior to PolyU, I gained valuable industry experience worked as machine learing engineer at Huawei Shanghai Institute and JD.com, two China’s leading tech companies. This experience provided me with practical insights into the deployment of AI in real-world scenarios, which inspired my pursuit of a PhD.
