Eugene Levin is Professor Emeritus in the School of Physics and Astronomy at Tel Aviv University. He is the founding father of the field of parton saturation and of the constituent quark model. Equations and approaches that bear his name include the Levin Frankfurt quark-counting rules, the Gribov Levin Ryskin nonlinear equation, the Levin Tuchin solution, and the Kharzeev Levin Nardi approach, reflecting only a selection of his many contributions to high energy physics.
