Professor Lee is Sara Shallenberger Brown Professor of Meteorology at Yale University, USA. His research and teaching concern the interactions between the terrestrial biosphere, the atmosphere and anthropogenic drivers. His areas of interest include boundary-layer meteorology, air pollution meteorology, meteorological instrumentation, remote sensing, and carbon cycle science. One focus of his research is on greenhouse gas fluxes in the terrestrial environment, including forests, cropland and lakes. Other ongoing projects deal with isotopic tracers in the cycling of carbon dioxide and water vapor and biogeochemical and biophysical effects of land use on the climate system. He is recipient of the 2015 Award for Outstanding Achievement in Biometeorology from the American Meteorological Society and currently serves as editor-in-chief for the international journal Agricultural and Forest Meteorology.
