The Johns Hopkins Workshops meet annually; they rotate among the participating Universities. The purpose of each workshop is to discuss outstanding issues in particle theory broadly interpreted. Topics can range from mathematical physics to cosmology. Typically, each workshop is restricted to one or two topics. Often, two topics to be discussed are chosen in such a way as to stimulate a dialog between two groups of physicists. Currently, the following Universities host the workshops: Chalmers University (Göteborg, Sweeden), Eötvös Loránd University (Budapest, Hungary), University of Florence (Florence, Italy), University of Heidelberg (Heidelberg, Germany), Johns Hopkins University (Baltimore, MD USA). (For a certain period, the Universities of Bonn (Germany) and Lanzhou (People’s Republic of China) also participated in the collaboration.)
In the permanent Organizing Committee each participating University is represented by two faculty members. The members of the Organizing Committee, often in consultation with an International Advisory Committee and local organizers, are responsible for the determination of the program of each forthcoming workshop.
