Director, HP Labs Israel
Abraham Lempel is a Senior HP Fellow, former director of the Advanced
Studies Program at HP Labs and former director of HP Labs Israel.
Lempel founded HP's Israel lab, which focuses on color printing algorithms, compression and coding algorithms,
image processing and computer vision algorithms and document
processing and understanding.
Widely known for his pioneering work in data compression,
Lempel is co-inventor of the Lempel-Ziv (LZ) data-compression
algorithm, a universal noiseless source-coding technique.
The work has won him numerous honors, including the Golden
Jubilee Award for Technological Innovation from the IEEE
Information Theory Society and the Paris Kanellakis Theory
and Practice Award from the Association for Computing Machinery
(ACM). He is also an IEEE
Fellow .
Lempel received his BSc, MSc, and DSc degrees from the Technion
- Israel Institute of Technology. He has been on the faculty
of Technion for more than three decades. He became a full
professor there in 1977 and was chairman of the department
of computer science from 1981 to 1984.
Lempel's association with HP Labs began in 1984 when he
visited the Palo Alto headquarters during a sabbatical. In
1994, with the establishment of HP Labs Israel, he became
a full-time HP employee, on special leave from Technion,
where he is still a chaired professor of Computer Science,
holding the Viterbi Chair in Information Systems.
Lempel has published over 70 papers in refereed journals
and holds 8 US patents. His principal research interests
are in the application of discrete mathematics to problems
in computer science and information theory.
