He obtained his PhD in ecology at the same institute. His main expertise are (1) surface flux measurements using different techniques (eddy covariance, Bowen ratio, and chamber methods, and so on); (2) vegetation water use, scaling up from leaf level to the ecosystem level; (3) carbon budget in terrestrial ecosystems and its response to the environmental factors; and (4) biogenic sources and sinks of greenhouse gases, mainly focus on N2O and CH4 exchange between plants and the atmosphere. By joining the PRoACC programme Jun Li will extend his research fields from ecology and micrometeorology to ecohydrology. His current researches focus on the interaction of climate and vegetation and their impacts on hydrological processes.
