Hongtao Qiao
  • Biography

    Prior to his PhD, Hongtao worked at Carrier Corporation developing advanced steady-state computer simulations for HVAC systems. During his PhD, he developed a comprehensive transient modeling framework for thermo-fluid systems to explore complex dynamic characteristics of vapor compression cycles. Currently, Hongtao works on the control-oriented multi-physical system modeling.
