As President, Prof. Zajfman has given priority to sustaining the Institute's high standards of excellence. He has led the establishment of several research schools, centers, and institutes. Under his direction, major funds have been invested in developing the Weizmann Institute's infrastructure. These efforts include the construction of a new conference center, a technical services facility, a building to house biochemical research, a cutting-edge preclinical facility, a state-of-the-art national center for personalized medicine, an integrated center for cancer research, and a new center for intelligent and advanced materials.
Under Prof. Zajfman’s leadership, the Weizmann Institute has increasingly become a hub of international science, with more international conferences and a growing number of foreign scientists, postdoctoral fellows, and students on campus. He is also a leader in advancing science education at the school level and science literacy among the public. To this end, he serves as Chair of the Davidson Institute of Science Education. He is also the guiding force behind the establishment of the Schwartz/Reisman Science Education Centers, which he also chairs.
