Jinfeng Liu, PhD
Area of Study / Keywords
Process Systems Engineering Mathematical and Molecular Modeling Energy Artificial Intelligence
Dr. Liu received the BS and MS degrees in Control Science and Engineering from Zhejiang University in 2003 and 2006, respectively. He received the PhD degree in Chemical Engineering from the University of California, Los Angeles in 2011. Before joining the University of Alberta in April, 2012, Dr. Liu was a postdoctoral researcher at the University of California, Los Angeles.
Dr. Liu's research interests are in the general areas of process control theory and practice with emphasis on model predictive control, networked control systems, process monitoring, and optimal control of chemical processes, energy systems, wastewater treatment plants, agriculture irrigation systems and biomedical systems. The long-term goal is to develop techniques enabling sustainable smart plant operations, in which physical processes, computations, and communication are integrated to address plant-wide safety and environmental and economic considerations.
