Scientific interests have been centering on atmospheric particle systems — aerosols, clouds and precipitation — and their interactions with climate and weather. Research covers a wide spectrum of topics, including aerosol/cloud physics, turbulence, light scattering, radiative transfer, remote sensing, and computer modeling. Current research concentrates on 1) development and evaluation of cloud-related parameterizations for models of various scales (from large eddy simulations to cloud-resolving models to numerical weather production models to climate models); 2) effects of anthropogenic aerosols on climate and climate change (direct, semi-indirect and indirect effects); 3) development of particle-resolved direct numerical simulation (DNS) models for studying turbulence-microphysics interactions and entrainment-mixing processes; 4) improving WRF-Solar to advance solar irradiance and wind forecast. Other related interests include 1) addressing atmospheric particle systems in the context of broader multiscale complex systems and big-data science, and 2) seeking applications of machine learning and causality analysis. Research activities integrate theoretical development, modeling, and observations. Developing an entirely new framework of scale-dependent models has been a goal of my research.

Research has resulted in 133 peer-reviewed publications in prestigious journals like Nature, Nature-Geophysics, and Physical Review Letters, numerous conference presentations, and invited talks. Work has been highlighted by Nature News, American Physical Society, American Institute of Physics, American Geophysical Union, DOE Office of Science, and various news media.
