From the original department – organic chemistry – the Weizmann Institute has grown to encompass all the natural and exact sciences. The departments, and the research groups in them, are purposely kept to human dimensions, which encourages scientists to cross their boundaries – both to engage in cross-departmental research and to forge paths to new areas of scientific exploration.
5 faculties: Biology, Biochemistry, Chemistry, Physics, Mathematics and Computer Science; and, in addition, the Feinberg Graduate School, each headed by a Dean
18 departments: Biological Regulation, Immunology, Molecular Cell Biology, Neurobiology, Biomolecular Sciences, Plant and Environmental Sciences, Molecular Genetics, Organic Chemistry, Structural Biology, Materials and Interfaces, Chemical Physics, Earth and Planetary Sciences, Physics of Complex Systems, Physics of Condensed Matter, Particle Physics and Astrophysics, Mathematics, Computer Science and Applied Mathematics, and Science Teaching
5 schools in the Feinberg Graduate School: The André Deloro Research School of Physical Science; the Solo Dwek and Maurizio Dwek Research School of Chemical Science; the Lorry I. Lokey Research School of Biochemical Science; the Ekard Research School of Biological Science; and the Moross Research School of Mathematics and Computer Science
The Scientific Council of the Institute consists of all of the full professors and the associate professors of the Institute as well as a number of representatives of other academic ranks and representatives of the student body.
The Council of Professors of the Institute, consisting of all the full professors, makes recommendations to the President and the Executive Board on all promotions to professorial grades and permanent appointments to the ranks of Senior Scientist and Senior Research Fellow.
