Jun 5-17, 2015, Dan traveled to China to meet with colleagues at several universities. His visit was coordinated by Professor Songhu Yuan at the China University of Geosciences (CUG) in Wuhan, and Professor Huaming Guo at CUG Beijing also hosted Dan during his visit. In Wuhan Dan met colleagues and gave presentations at CUG as well as Huazhong University of Science and Technology (hosted by Professor Jiakuan Yang) and Huazhong Agricultural University (hosted by Professor Xionghan Feng). In addition to visiting CUG in Beijing, Dan was hosted by Professor Chongyuan Jing at the Research Center of Eco-Environmental Science of the Chinese Academy of Science and Professor Jinren Ni at Peking University.
