Ehud Shapiro is an multidisciplinary scientist, entrepreneur, artist, and political activist. He earned his PhD in computer science from Yale in 1982. Since that time, he has worked at the Weizmann Institute of Science, where he currently holds the Harry Weinrebe Professorial Chair in Computer Science and Biology. He developed the discipline of concurrent logic programming and the distributed logic programming language Concurrent Prolog at Weizmann. He founded Ubique Ltd., the first internet social networking software start-up, which he then sold to IBM, where its technology was the basis of Sametime, IBM's successful corporate network communication and collaboration product. Upon return to Weizmann in 1998, Shapiro switched to biology, and led research projects on biomolecular computers, synthetic biology, and human cell lineage reconstruction. Since 2017 he has been working on digital democracy with collaborators and a research team he formed at Weizmann.
