David Harel(Hebrew:דוד הראל;born 12 April 1950) is a computer scientist, currently serving as President of theIsrael Academy of Sciences and Humanities.He has been on the faculty of theWeizmann Institute of ScienceinIsraelsince 1980, and holds the William Sussman Professorial Chair of Mathematics. Born in London, England, he was Dean of the Faculty of Mathematics and Computer Science at the institute for seven years.

Biography

[edit]

Harel is best known for his work ondynamic logic,computability,database theory,software engineeringandmodelling biological systems.In the 1980s he invented the graphical language ofStatechartsfor specifying and programming reactive systems, which has been adopted as part of theUMLstandard. Since the late 1990s he has concentrated on a scenario-based approach to programming such systems, launched by his co-invention (with W. Damm) ofLive Sequence Charts.He has published expository accounts of computer science, such as his award-winning 1987 book "Algorithmics: The Spirit of Computing" and his 2000 book "Computers Ltd.: What TheyReallyCan’t do ", and has presented series on computer science for Israeli radio and television. He has also worked on other diverse topics, such asgraph layout,computer science education,biological modeling and the analysis and communication ofodors.

Harel completed his PhD atMITbetween 1976 and 1978. In 1987, he co-founded the software companyI-Logix,which in 2006 became part of IBM. He has advocated building a full computer model of theCaenorhabditis elegansnematode, which was the first multicellular organism to have its genome completely sequenced. The eventual completeness of such a model depends on his updated version of theTuring test.He is a fellow of theACM,theIEEE,theAAAS,and theEATCS,and a member of several international academies. Harel is active in a number of peace and human rights organizations in Israel.
