Biography:

Dr. Johnny Luo is an Associate Professor at the Department of Earth and Atmospheric Sciences (EAS) of the City College of New York with specialty in the area of satellite remote sensing and cloud dynamics. He received his BS from Peking University (1997) and PhD from Columbia University (2003) in Atmospheric Science. For the past 17 years, Dr. Luo has been working closely with NASA and NOAA. He is a member of NASA's CloudSat/CALIPSO mission science Team and NOAA's Climate Data Record (CDR) Team. Dr. Luo also participates in airborne field campaigns and recently served as a Science Team Leader for NASA's SEAC4RS mission.
