Research Interests

I am an atmospheric scientist. My research has focused on diverse topics of climate change, including atmospheric chemistry, stratosphere-troposphere exchange, land-atmosphere interactions and volcanoes. Currently, I intensively work on the DOE Energy Exascale Earth System Model (E3SM) and Atmospheric Radiation Measurement (ARM) observational data.
