Yonghong Hu,
 Ph.D. Professor, Executive Director of Shanghai Chenshan Botanical Garden, Vice Director of Shanghai Chenshan Plant Research Center of Chinese Academy of Sciences (SCPRC, CAS), leader of the Tree Peony Group in SCPRC. Dr. Hu was born in October 1968, in Yanshi, Henan. He earned his Ph.D. in Landscape Gardening from Beijing Forestry University in 1997. In 2004-2005, he was trained at Kew Gardens in Botanical Garden Management. Dr. Hu has made tremendous contribution to the long-term conservation of flora in East China, the development of botanical gardens in Shanghai, and biological research of tree peony in East China. He has been awarded the leading talent in Shanghai, the National May 1 Labor Medal and the special allowances from the State Council among many others from 2004 to 2015. He has undertaken over 50 projects funded by Shanghai and national scientific departments, published more than 140 research papers, 7 monographs, 8 patents, and registered 15 new varieties.
