Research Focus

Air pollutant origin, transport, and formation; aerosol chemistry, physics, and optics; indoor air quality


Dr. Liu received his Ph.D. from the Scripps Institution of Oceanography, University of California San Diego. Following this, he conducted postdoctoral research at Los Alamos National Laboratory and the University of Colorado Boulder. He has worked as a scientist at the National Oceanic and Atmospheric Administration (NOAA) and as a faculty member at the University of Science and Technology of China before joining the Research Division of the California Air Resources Board. Dr. Liu joined Northeastern University in January 2024.

Dr. Liu is an atmospheric chemist and air resources engineer. His work combines field observations, laboratory measurements, and model refinement to enhance the predictive understanding of how emissions affect air pollution and climate. His research interests focus on studying the impact of airborne particulate matter and trace gases on air quality and climate, using advanced techniques such as mass spectrometers and spectroscopy. Dr. Liu’s work has led to the development of analytical methods that have advanced our understanding of the sources and formation mechanisms of air pollutants.

Dr. Liu is committed to leveraging the best science and technology available to identify viable pathways to mitigate air pollution and climate change. His work aims to bridge the gap between scientific research and policy implementation, with the ultimate goal of improving public health and environmental sustainability.

Air Resources Research Group

Air Resources Research Group is dedicated to pushing the boundaries of environmental research and promoting sustainability.

We explore air pollutant emissions, transport, fate, and their environmental and climate impacts. Leveraging cutting edge methods and techniques, we unravel the complexities of these issues. All of our efforts converge towards the overarching goal of enhancing environmental resilience.
