Prof. Dr. Kuidong XU, male, born in December 1969. He is a Principle Investigator in the Institute of Oceanology, Chinese Academy of Sciences (IOCAS) and director of Laboratory of Marine Organism Taxonomy and Phylogeny, IOCAS. He is also a professor of the University of Chinese Academy of Sciences. He received his Ph.D. Degree from the Ocean University of China in 1999. Then he worked as a postdoctor in Inha University, Korea during 1999-2002 and in Salzburg University, Austria during 2002-2005. Since April 2005, he has been working in the IOCAS to date. His main research interests include the taxonomy, biodiversity and phylogeny of marine animals. Recently, he focuses mainly on the biodiversity and distribution of megabenthos as well as microbial eukaryotes from seamounts in the Western Pacific Ocean, a key program supported by the Natural Science Foundation of China. He has published about 200 peer-reviewed papers including 101 articles in SCI-indexed journals, and four monographs.
