Zurich, Switzerland, 25 May 2005 — IBM announced today that
five employees will be named IBM Fellow — the company's most
prestigious technical honor — among them Dr. Evangelos Eleftheriou
of the Zurich Research Laboratory. The five honorees drive innovation
in areas as diverse as nanotechnology, computer design and data
storage.
There have been only 185 IBM Fellows in the past 42 years, including
61 active employees with the newly-named Fellows. IBM Fellows are
given freedom and flexibility to pursue creative achievements and
typically work on special projects or research initiatives that
lead the company in exciting new directions.
 Evangelos
Eleftheriou, whose pioneering work in recording and communications
techniques established new standards of performance in hard disk
drive technology, heads the Storage
Technologies group of the Zurich Research Laboratory. He has
published more than 90 papers and four book chapters, and holds
25 US patents. His work has been honored numerous times. In 2003,
he was co-recipient of the prestigious 2003 IEEE Communications
Society Leonard G. Abraham Prize in the field of Communications
Systems, and in 2001, he was elected Fellow of the Institute of
Electrical and Electronics Engineers (IEEE) for the invention of
noise-predictive maximum likelihood sequence detection.
He is most noted for his work on reduced-state sequence detection/decoding
in conjunction with noise prediction for magnetic recording and
filtered multi-tone modulation techniques for communications systems.
His concept of "Noise-Predictive Maximum Likelihood" (NPML)
detection has become the core of a new architecture developed for
the read channel of hard-disk drives (HDD), and has since become
the de facto industry standard. Its deployment in IBM and Hitachi
HDD read channels led to an increase of linear density of more than
50% over that of conventional methods. NPML read-channel modules
have shipped in server-class, desktop, and mobile HDDs as well as
in the Microdrive.
Over the years, Evangelos Eleftheriou's research has covered a
wide variety of subjects, ranging from communications and information
theory to signal processing and coding for transmission and recording
systems. His current research is focused on advanced signal processing,
coding, and servo control techniques for improving the reliability
and performance of tape systems, as well as for increasing their
areal density and storage capacity. With his team he is also currently
exploring alternative storage technologies based on nanotechnology.
Specifically, these novel storage technologies are atomic force
microscopy (AFM)-based probe-storage techniques, better known as
"millipede".
Evangelos Eleftheriou received a bachelor's degree in Electrical
Engineering from the University of Patras in Greece in 1979, and
M.Eng. and Ph.D. degrees, also in Electrical Engineering, from Carleton
University, Ottawa, Canada, in 1981 and 1985, respectively. He joined
IBM Research in 1986.
