Dr. Liu is a tenured Professor in the Department of Physical Sciences at Embry-Riddle Aeronautical University in Daytona Beach, FL. His research areas are the dynamics and composition of the middle and upper atmosphere, and their relationships to the atmospheric global circulation and space weather. His current research interests are in the gravity wave and turbulence processes and their impacts on atmosphere composition, global circulation, and space weather. Dr. Liu manages the Andes Lidar Observatory, located at Cerro Pachón, Chile. ALO houses several advanced ground-based remote sensing instruments, including a sodium resonance/fluorescence Lidar, airglow imagers and a meteor radar, used to measure atmospheric wind, temperature and wave signatures. The ALO website is at http://lidar.erau.edu.

Dr. Liu has been the PI of a number of projects supported by grants from the National Science Foundation. His current projects include an NSF Major Research Instrumentation project that will deploy a advanced meteor radar at ALO, and an NSF Aeronomy project that supports the long-term operation of the ALO sodium lidar. Dr. Liu have advised multiple MS and PhD students. He is a senior member of IEEE and a member of American Geophysical Union and American Meteorological Society. Dr. Liu has 77 peer-reviewed journal publications with h-index of 29 and over 2100 citations according to Google Scholars as of May 2019.
