Dr. Qian joined PNNL in 2000 and currently is a senior scientist, group lead and associate division director in Atmospheric Sciences and Global Change division.

Dr. Qian's research passion has been the climate modeling and the aerosol-climate-water interactions. He is one of the pioneer scientists in studying the China aerosol and its climatic impact. He has been leading projects investigating the impacts of snow and ice impurities on climate and water resource. He is also interested in the land-atmosphere-cloud interaction, including the impact of urbanization and irrigation. Recently he has been working on the uncertainty quantification in climate modeling.

Dr. Qian's research has generated tremendous impacts among the scientific community and public. His research is prominently featured by the Nature and Science, as well as Associate Press, New York Times, BBC, China Daily, and many other news media. Dr. Qian has published more than 110 peer-reviewed papers in international journals. His papers have been cited more than 5000 times with a H-index of 42. He has been invited to speak at dozens of workshops and conferences including AMS, AGU, AOGS and EGU. He is a co-chair of an international working group for Global Monsoons Modeling Inter-comparison Project and director of international Workshop on Uncertainty Quantification in Climate Modeling and Projection. He is a contributing author of IPCC report. He served at NASA and DOE proposal review panels and also serves as editor for "Advances in Atmospheric Sciences" and "Atmospheric Chemistry and Physics".
