Hello, I’m LIU Huan, a professor in Tsinghua University. I got my bachelor’s degree in environmental engineering from Tsinghua University in 2004, and then joined Dr. Kebin He’s research group in Tsinghua and received my PhD in 2009. I then joined Dr. Matthew Barth’s research group at UC-Riverside and Dr. James Lents’ International Sustainable Systems Research Center (ISSRC) in the US for a joint post-doctoral research position in 2009- 2010 before coming back to Tsinghua as an assistant professor in the end of 2010. More information please see the Resume tab. Air pollution and climate change are two major challenges but also opportunities in the contemporary atmospheric science field, and transportation has become one of the most determining and fast increasing driving factors for those challenges. My major research is to improve the understanding and predictability of contemporary atmospheric environment by coupling traffic, material flow and atmospheric system. We work on developing:

  1. Theory and technology of dynamic traffic emission models for street, regional and global scales

  2. A multi-scale air quality coupling model adaptable for complex urban underlying surface environment

  3. Regional transportation emission control scheme and global emission reduction framework theory correlated to supply chain More information please see the Research and Publications tab.
