John Cronan Kieffer (born 1945) is an American mathematician best known for his work in information theory, ergodic theory, and stationary process theory.

Education[edit]

Kieffer received his elementary and high school education in St Louis, Missouri, a bachelor's degree in applied mathematics in 1967 from University of Missouri Rolla, and a master's degree in mathematics in 1968 from University of Illinois Urbana-Champaign. In 1970, under Robert B. Ash, he received the Ph.D. degree in mathematics from University of Illinois Urbana-Champaign with thesis A Generalization of the Shannon-McMillan Theorem and Its Application to Information Theory.[1][2]

Work history[edit]

In 1970 Kieffer became an assistant professor at Missouri University of Science and Technology, where he eventually became a full professor.[3] In 1986 he became a full professor at University of Minnesota Twin Cities.[4] Kieffer held visiting appointments at Stanford University, University of Illinois Urbana-Champaign, ETH Zürich, and University of Arizona. He has been the supervisor for 6 Ph.D. theses.[1]

Professional activities[edit]

During the 1980s, Kieffer was Associate Editor of the IEEE Transactions on Information Theory.[5] In 2004, Kieffer was co-editor of a special issue of the IEEE Transactions on Information Theory entitled "Problems on Sequences: Information Theory and Computer Science Interface". [6] He is a Life Fellow of the Institute of Electrical and Electronics Engineers "for contributions to information theory, particularly coding theory and quantization".[7]

Impact[edit]

Kieffer has over 70 journal publications in the mathematical sciences.[11] His research work has attracted over 3000 Google Scholar citations,[12] over 500 MathSciNet citations[13] and over 1000 IEEE Xplore citations.[3] Some of these works have been cited as prior art on various United States patents.[14] In 1998, the IEEE Transactions on Information Theory published a special issue consisting of articles that survey research in information theory during 1948–1998. Two of these articles include discussions of Kieffer's work, namely, the article Lossy Source Coding[15] by Toby Berger and Jerry Gibson, and the article Quantization[16] by Robert M. Gray and David Neuhoff. In addition, the textbook Transmitting and Gaining Data[17] by Rudolf Ahlswede presents several aspects of Kieffer's work.
