Fan Chung

The doctoral dissertation of Fan Chung was effectively two-thirds complete just one week after her advisor, Herbert Wilf, first proposed a problem in Ramsey theory. Having arrived at the University of Pennsylvania from Kaohsiung, Taiwan, where she was born in 1949, Chung rapidly established a reputation for producing major mathematical results under tight time constraints.

Academic Formation and Early Research

Chung completed her undergraduate studies at the National Taiwan University before moving to the United States. During her graduate tenure at the University of Pennsylvania, she earned an M.S. in 1972 and a Ph.D. in 1974. Her early academic proficiency was marked by achieving the highest score in the department qualifying exam. This performance led to her intensive collaboration with Herbert Wilf and the development of new proofs for existing problems in combinatorics.

Industry Tenure at Bell Laboratories

Upon completing her doctorate, Chung joined the Mathematical Foundations of Computing Department at Bell Laboratories in Murray Hill, New Jersey, in 1974. Working under Henry Pollak, she engaged in multi-disciplinary research. Following the 1983 breakup of the Bell Telephone Company, she transitioned into a management role, overseeing a research unit. She maintained this position through the company's evolution into Bellcore, during which time she was awarded a fellowship to spend a sabbatical at Harvard University.

Specialization in Information Networks

Her research primarily addresses spectral graph theory, extremal graph theory, and the mechanics of random graphs. Her work gained significant relevance as information technology expanded, specifically regarding the generalization of the Erdős–Rényi model for large-scale networks. She has applied these theories to analyze web search algorithms, biological databases, and social connectivity. In 1998, she returned to academia as the Paul Erdős Professor in Combinatorics at the University of California, San Diego.

Professional Recognition and Service

Chung has contributed to the mathematical community through her roles on the editorial boards of over a dozen international journals and as the editor-in-chief of Internet Mathematics since 2003. Her career includes an invitation to lecture at the International Congress of Mathematicians in 1994 and a plenary session at the 2008 Annual Meeting of the American Mathematical Society. She was elected to the United States National Academy of Sciences in 2024.
