HP Senior Fellow Robert E. Tarjan has been named winner of the 2004 Blaise Pascal Medal in Mathematics and Computer Science for his contributions to computer science and for the development of fundamental computer algorithms.

Tarjan, who has also received the prestigious A.M. Turing Award, is a well-known expert in the design and analysis of computer algorithms. He is the inventor or co-inventor of the most efficient known algorithms and data structures for problems in a wide variety of application areas.

The Blaise Pascal Medal was established by European Academy of Sciences in 2003 to recognize an outstanding and demonstrated personal contribution to science and technology and the promotion of excellence in research and education. The academy awards medals in three fields besides mathematics: natural sciences, engineering and physics.

Tarjan was one of two winners of the mathematics prize.The other was Prof. Lev Kudryavtsev, a Russian mathematician who was honored for contributions to the theory of functions, topology;and mathematical education.

At HP, Tarjan is responsible for identifying key technological trends and determining how the company can best respond, as well as for helping to coordinate and strengthen research and development efforts.

At the same time, he continues his own research in data structures, algorithms and security and teaches at Princeton University, where he is the James S. McDonnell Distinguished University Professor of Computer Science.

Tarjan has published more than 170 refereed journal articles and book chapters. A member of the National Academy of Sciences, the National Academy of Engineering and other learned societies, he was awarded the first Nevanlinna Prize in Information Science in 1983, the Turing Award in 1986 and the Paris Kanellakis Award in Theory and Practice in 1999.

He is also a fellow of the Association for Computing Machinery (ACM) and the American Academy of Arts and Sciences,

Dr. Tarjan received a bachelor's degree in mathematics from the California Institute of Technology in 1969 and an master's and doctorate . in computer science from Stanford University in 1971 and 1972, respectively.

Blaise Pascal was a French mathematician, physicist, theologian who invented a mechanical adding machine. Among other things, he is known for Pascal's Wager, an argument for the belief in God based on probabilities. Pascal's triangle, a way to present binomial coefficients, bears his name, as does the Pascal computer programming language.
