About Xiaoqi (Clare) Liu

Dr. Liu is an Assistant Professor at the Durham School of Architectural Engineering & Construction. Prior to joining University of Nebraska-Lincoln, she worked as a Research Engineer at Pacific Northwest National Laboratory (PNNL). She was involved in several industry- and federal-funded research projects related to advanced building controls, occupant eco-feedback programs, building-to-grid integrations, and building energy standards during her time at Purdue University and PNNL. Her research combines Artificial Intelligence (AI) with physical knowledge of building systems to create scalable, efficient and reliable solutions for intelligent operation planning that optimize building energy use and demand, while serving occupants’ needs.
