Benjamin Kedem, who joined the University of Maryland in 1975 as an Assistant Professor, holds a PhD. (1973) in statistics from Carnegie-Mellon University, Pittsburgh, and specializes in inference for space-time stochastic models. His research has been recognized by several awards including IEEE W.R.G. Baker award (1988), award from the Armament Development Authority, Israel (1984), NASA/Goddard Exceptional Achievement Award (1997), and IBM Faculty Award (2006). He is a Fellow of the American Statistical Association.

Kedem has published in statistics, engineering, and scientific journals including the Annals of Statistics, Journal of the American Statistical Association (JASA), Biomertrika, IEEE Tr. on Information Theory, Journal of the Acoustical Society of America (another JASA), Journal of Applied Meteorology, and Journal of Geophysical Research.

When nobody sees, let alone hears, he likes to play on his old accordion, harmonica, or both simultaneously, such tunes as "Good Night Irene," versions of "Karabushka" (Russian), Klezmer music, etc. These hardly change over the years. Kedem is also an avid soccer player.

Honors and Awards 

Fellows
American Statistical Association, 1999

Other awards
Goddard Exceptional Achievement Award, 1997

 

Time series analysis, space-time statistical problems, and combination of information from several sources. In particular, he has worked on higher order crossings, contraction mapping in spectral analysis, the Rice formula, the threshold method, partial likelihood and spatial prediction.
