Edward B. Saff

His research deals with approximation of complex functions by polynomials and rational functions, approximate solutions of differential equations, Padé approximants, geometry of polynomials, special functions, Hardy spaces, conformal mappings (including numerical analysis). and potential theory (minima of energy under boundary value constraints or external fields). He is the author or coauthor of over 240 research articles, the coauthor of 9 books, and the coeditor of 11 volumes. He was the coeditor, with Theodore J. Rivlin, of a volume of Joseph L. Walsh's Selected Works published in 2000. Since 2007 he is an ISI Highly Cited Researcher.

For the academic year 1978–1979 Saff was a Guggenheim Fellow at the University of Oxford. In 2012 he was elected a Fellow of the American Mathematical Society. He was elected in 2013 a Foreign Member of the Bulgarian Academy of Sciences and made in 1987 an Honorary Professor of the Zhejiang Normal University in China.

Saff received in 1964 his bachelor's degree from the Georgia Institute of Technology and in 1968 his PhD from the University of Maryland, College Park under Joseph L. Walsh with thesis Interpolation and Functions of Class H (k, a, 2). As a postdoc he was a Fulbright Fellow at Imperial College London from 1968 to 1969. At the University of South Florida he was from 1969 to 1971 an assistant professor, from 1971 to 1976 an associate professor, from 1976 to 1986 a full professor, and from 1986 to 2001 a distinguished research professor. At Vanderbilt University he is, since 2001, a professor and director of the Center for Constructive Approximation and was from 2004 to 2007 the Executive Dean of the College of Arts and Sciences.
