After obtaining her M.Sc. Fang Fang worked at the
Chinese Academy of Sciences as a research associate in the Division of Ichthyology in Beijing. While there she undertook extensive field work, studying fish in a number of Chinese rivers. She also assisted Professor
Li Sizhong in conducting a review of the distribution of the important Chinese
carp species. It was during her time at the Chinese Academy of Sciences that she first travelled to Sweden, working for three months from October 1992 as a visiting scientist at the
Swedish Museum of Natural History under a scholarship supported by the
Royal Swedish Academy of Engineering Sciences and the Chinese Academy of Science. During this stay she mainly worked on the sorting and identification of the collection of freshwater fish from Sri Lanka, most of which actually came from the Museum of Zoology at
Lund University. This work led Fang Fang to submit a proposal to carry out a
Ph.D. revising the
cyprinid genus Danio at the Department of Zoology at
Stockholm University, which was accepted in 1993. She was granted laboratory space at the Swedish Museum of Natural History and in 1996 she obtained a full Ph.D. position. While studying for her Ph.D. she travelled widely to South America and south Asia, and even returned to China to collect specimens in
Yunnan. She completed her Ph.D.,
Phylogeny and species diversity of the South and Southeast Asian cyprinid genus Danio Hamilton (Teleostei, Cyprinidae) in 2000. After completing her Ph.D. she worked for the
European Union funded ECOCARP project searching for new species which could be used for
aquaculture in China, this lasted from 2001 to 2003. Following this she worked for the Swedish
Fishbase team and she was secretary of the European Ichthyological Association from 2004 up to 2009. She was also a member of the Japanese Ichthyological Society, the
American Society of Ichthyologists and Herpetologists, the Sveriges Fiskforskares Förening (the "Swedish Fisheries Association"), the Chinese Society of Ichthyologists, and the Chinese Society of Zoologists. ==Personal life==
