Fan Rong K Chung Graham (金芳蓉, pinyin: Jīn Fāngróng) (born October 9, 1949 in Kaohsiung), known professionally as Fan Chung, is a mathematician who works mainly in the areas of spectral graph theory, extremal graph theory and random graphs, in particular in generalizing the Erdős-Rényi model for graphs with general degree distribution (including power-law graphs in the study of large information networks).
She is the Akamai Professor in Internet Mathematics at the University of California, San Diego (UCSD) in the United States since 1998. She received her doctorate from the University of Pennsylvania in 1974, under the direction of Herbert Wilf. After working at the Bell Laboratories and Bellcore for nineteen years, she joined the faculty of the University of Pennsylvania as the first woman tenured professor in mathematics. She serves on the editorial boards of more than a dozen international journals. Since 2003 she is the editor-in-chief of Internet Mathematics. She has given invited lectures in many conferences, including International Congress of Mathematicians in 1994, and a plenary lecture on the mathematics of PageRank at the 2008 Annual meeting of American Mathematical Society.
Chung has two children, the first born during her graduate studies, from her first marriage She has been married to the mathematician Ronald Graham since 1983. The couple were close friends of the mathematician Paul Erdős, and have both published papers with him; thus, both have Erdős numbers of 1.
She has published more than 200 research papers and three books:
