**Daniel Zajfman** (Hebrew: דניאל זייפמן; born June 7, 1959) is an Israeli [physicist](/source/Physicist) whose main research interests are centered on the physics of simple [molecular ions](/source/Molecular_ion). On December 1, 2006, he was elected as the tenth president of the [Weizmann Institute](/source/Weizmann_Institute).

## Early life

Daniel Zajfman was born in [Brussels](/source/Brussels), Belgium. He joined the [Hashomer Hatzair](/source/Hashomer_Hatzair) movement while studying at the [Athénée Robert Catteau](/source/Ath%C3%A9n%C3%A9e_Robert_Catteau).[1] In 1979 he emigrated to Israel where he met his wife, Joëlle Hayoun. In 1983 he graduated in [Physics](/source/Physics) (B.Sc.), at the [Technion](/source/Technion), Israel Institute of Technology, [Haifa](/source/Haifa). He continued his studies at the Technion and in 1989 received his PhD, in [atomic physics](/source/Atomic_physics). He conducted his post-doctoral at the [Argonne National Laboratory](/source/Argonne_National_Laboratory), [Illinois](/source/Illinois), United States. (1989–1991)

## Career

In 1991 he returned to Israel and began his career as a senior scientist at the Dept. of [Particle Physics](/source/Particle_Physics) ([Weizmann Institute](/source/Weizmann_Institute) of Science). In 1997, he was appointed Associate Professor and was promoted to full professor in 2003. Since 2001, he has been an external member of the [Max Planck Institute for Nuclear Physics](/source/Max_Planck_Institute_for_Nuclear_Physics) in [Heidelberg](/source/Heidelberg), Germany, and in 2005, he was appointed as a Director at this [Max Planck Institute](/source/Max_Planck_Institute).

On December 1, 2006, he was elected as the tenth president of the [Weizmann Institute](/source/Weizmann_Institute), the youngest ever. He was in turn succeeded in 2019 by [Alon Chen](/source/Alon_Chen).[2]

On January 1, 2020, he was elected as the Chair of the Academic Board of the Israel Science Foundation.

In 2023 he received the [Harnack Medal](/source/Harnack_Medal).[3] for his contributions to the advancement of science and German-Israeli cooperation

## Research and patents

His research focuses on the [reaction dynamics](/source/Reaction_dynamics) of small [molecules](/source/Molecule) and how they influence the composition of the [interstellar medium](/source/Interstellar_medium). He recreates the conditions of [outer space](/source/Outer_space) in the laboratory using special devices called '[ion traps](/source/Ion_trap)' or '[storage rings](/source/Storage_ring)'. In these devices, he is able to briefly store and measure the properties of small amounts of material, as little as a few hundred [atoms](/source/Atom) or molecules-worth, under the extreme conditions of [interstellar](/source/Interstellar_space) space (especially very low temperatures and low densities). Some of his research has focused on the puzzle of how complex molecules are formed in outer space.
