His research interests involve the Permian and Triassic conodonts and stratigraphy correlation and has also worked at University of Leicester, Leicester, UK, as a visiting researcher (2007-2008). He has published more than 30 papers in many peer-reviewed journals as the main author or the co-author, covering Science, Geology, Earth Science Reviews, Global and Planetary Change, Lethaia, Palaios, Journal of Earth Science, Journal of Asian Earth Sciences as well as Palaeogeography, Palaeoclimatology, Palaeoecology. Prof. Kexin Zhang is now Professor at China University of Geosciences, Wuhan. His research interests involve Micropaleontology (conodont), Sequence Stratigraphy, Cenozoic sedimentary and uplift of the Tibet Plateau. He has won National Science and Technology Award in 2002 and Special Award of the National Science and Technology Progress Award in 2011. As one of major authors, he firstly proposed the conodont Hindeodus parvus as the index fossil for the Permian-Triassic boundary at the GSSP section, Meishan Section D of South China. He has published more than 240 papers in many peer-reviewed journals as the main author or the co-author and also authored a number of books and chapters. Prof. Jianxin Yu works at the State Key Laboratory of Biogeology and Environmental Geology and School of Earth Sciences, China University of Geosciences, Wuhan, China.
