Daniel Bar-Tal is Professor Emeritus at the School of Education, Tel Aviv University. He is best known for his research on the socio-psychological foundations and dynamics of intractable conflicts. In addition to his academic work, he is a practitioner, activist and mentor (teacher). His most influential theoretical contribution is the development of a systematic and holistic conception of the dynamics of interethnic bloody and lasting conflicts: how they erupt, escalate and possibly de-escalate (see his book Intractable conflicts: Socio-psychological foundations and dynamics). In addition, he is an authority on the Israeli-Arab/Palestinian conflict, suggesting a comprehensive socio-political psychological analysis of its foundation, continuation and maintenance.
