Our research group studies the interactions between the biosphere and the atmosphere to understand how vegetation affects atmospheric chemistry and climate. The biosphere is a living and dynamic component of the Earth System, and is constantly responding to the world around it. Our research focuses on understanding how emission from the biosphere can affect atmospheric chemistry and air quality, as well as understanding how changes at the land surface can affect regional climate.
