Speaker: Xue-Yan Liu, is a professor in the School of Earth System Sciences of Tianjin University. He got a PhD degree of Geochemistry in 2008 in Institute of Geochemistry, CAS, then worked as postdoctoral fellows under the JSPS Programs for Foreign Researchers and for Next Generation World-Leading Researchers from 2009-2014. He has won the Excellent Young Scientist (2015) and Key Project of NSFC (2017), the outstanding Youth Funds of Tianjin (2017),national Youth Talents, and participated the State Key Projects of Research and Development Plan on atmospheric pollution and causes, global change and responses.
Introduction: Nitrogen is a nutritional element for earth life, but human activities have caused a rapid and continuous increase of reactive nitrogen in the atmosphere since the early of 20th Century, which produces secondary particulates and influences the air quality, meanwhile elevates atmospheric nitrogen inputs to terrestrial ecosystems and further induces changes in plant diversity and carbon fixation, soil acidification, eutrophication. Most research works in Dr. Liu’s lab now focus on natural stable isotopes and new applications for sources and processes of nitrogen pollutants, nitrogen biogeochemistry in terrestrial ecosystems and their responses to environmental changes. The overarching aim is to provide in situ geochemical knowledge for better mitigating N pollution and evaluating its negative effects.
