My research interest is clouds and convection. Most of my past and ongoing research activities focus on space-borne remote sensing, and use of remote sensing data to investigate convective dynamics . More recently (since 2012), I've started participating in airborne field campaigns to study convective transport of pollutants and trace gases, including flying into and around convective storms (heck of a ride! see video) and hurricane (photos below show our adventure into Hurricane Ingrid in 2013). An important purpose of my research is to gain process-level understanding of clouds and convection to help improve their representations in weather and climate models.

On satellite remote sensing, I am a member of NASA CloudSat/CALIPSO Science Team. On field work, I served as a Science Leader of NASA SEAC4RS field campaign (photos below), and a member of NSF's CONTRAST and ACCLIP . On modeling, I am a PI of NASA's MAP (Modeling, Analysis and Prediction) Program, focusing on assessing GCM cumulus parameterizations using satellite-based estimates of convective mass flux. I am also a member of NASA Decadal Survey, Aerosol and Cloud, Convection and Precipitation (ACCP) Science Community Committee (SCC), an academic Advisory Board for NASA.

My teaching interest is Atmospheric Science in general with emphasis on satellite remote sensing and cloud-water vapor-climate topics. Throughout my class, I will involve students with my own research, especially those related to satellite remote sensing and atmosphere/climate data analysis.

It's important to note that Atmospheric Science is a quantitative field. Strong math, physics and programming backgrounds are important prerequisites. Here is a good introduction to the modern Atmospheric Science prepared by the National Center for Atmospheric Science (NCAR).

We are recruiting graduate and undergraduate students to work in the area of tropical convection and convective transport of trace gases. Atmospheric Science (or similar background) and strong programming skills are needed. Contact me if you are interested.

These three photos nicely summarize the theme of the group: Big Apple and Deep Convection! What's the 4th photo stand for? Well, that's a reminder of an important character needed for success in academia - patience!
