Prof. Irit Sagi

More info

Born in Israel, Prof. Irit Sagi attended university in Washington, DC, receiving a BSc degree in Physical Chemistry from American University (1988), and PhD degree in biophysics/bioinorganics from Georgetown University (1992). She returned to The Weizmann Institute to perform postdoctoral research in the group of Prof. Ada Yonath, laureate of the 2009 Nobel Prize in Chemistry. Prof. Sagi continued her postdoctoral studies at the Max-Planck Institute in Berlin, and joined the faculty of Chemistry at the Weizmann Institute in 1998. Between 2005-2006 she spent a sabbatical as a visiting professor at Harvard University and at Novartis research institute, USA. She became the dean of the Feinberg Graduate School in 2014 and is the incumbent of the Maurizio Pontecorvo Professorial Chair. In December, 2019, she finished her term as dean and assume the position of Vice President for Technology Transfer.

Prof. Irit Sagi is developing and applying unique, multidisciplinary and biophysical approaches to investigate tissue and extracellular remodeling molecular processes. Merging together real-time spectroscopic and molecular imaging approaches, she was the first to reveal the complex dynamic molecular nature of extracellular remodeling enzymes including matrix metalloproteinases and lysyl oxidases (MMPs and LOX), a group of human enzymes linked to, developmental biology, cancer, inflammation, fibrosis and infectious diseases. Insights derived from these studies led her to design a new class of inhibitory antibodies that thwart the negative action of these enzymes. These prototype antibodies are currently being developed for clinical use in inflammatory, and cancer diseases by a start company, Mabtrix ltd. Prof. Sagi continues to develop novel integrated experimental tools tailored to decipher the extracellular matrix molecular remodeling code at near atomic resolution in healthy and diseased tissues. Her unique biophysical approach is used to decipher molecular mechanisms of dysregulated tissue proteolysis/remodeling and to develop a new generation of safe and effective drugs and in vivo molecular modulators. Recently, she demonstrtaed a novel use for proteases in promoting and increasing the rate of embryo implantation in mammals. This discovery led her to establish a new startup company, NanoCell, aiming at developing this technology in Livestock and human. Prof. Sagi is the incumbent of the Maurizio Pontecorvo Professorial Chair. She has more than 200 publications in peer reviewed scientific journals and editor of two books. Prof. Sagi earned the Landau Prize of Mifal Hapais for Biochemistry in 2017 and the Juludan Prize for outstanding research projects in the exact sciences and advanced medicinal technologies in 2013. In 2006, she was named Inventor of the Year by the Weiznmann Institute’s Yeda Ltd. Three years prior, she was awarded the Weizmann Institute Scientific Council Prize for Chemistry, and in 2000, she received the Jakubskind-Cymerman Research Prize. Fron 2009-20014 she has been the president of the Israel Biophysical Society and she is currently the president of the Israel Matrix Biology Society. Prof. Sagi is a member of the International Board of Directors of Future Fund for promoting Israel-Germany relations and she is a member of the UK Israel Science Council.

Prof. Daniel Zajfman

More info

Born in Belgium in 1959, Daniel Zajfman moved to Israel in 1979. He received a B.Sc. in 1983 and a Ph.D. in 1989 from the Technion – Israel Institute of Technology in Haifa, Israel, in atomic physics. After working as a consultant for Elscint in Haifa, Prof. Zajfman spent two years at the Argonne National Laboratory, near Chicago, as a postdoctoral fellow. He returned to Israel in 1991 and joined the staff of the Weizmann Institute's Department of Particle Physics as a senior scientist. He was appointed associate professor in 1997 and full professor in 2003. Since March 2001, he has been an external member of the Max Planck Institute of Nuclear Physics in Heidelberg, Germany, and in 2005, he was appointed Director in that institute. In November 2006, Prof. Zajfman was elected the tenth President of the Weizmann Institute by Institute’s Board of Governors. He assumed this position on December 1, becoming, at 47, the youngest president the Institute ever had.

Prof. Zajfman's research interests focus on atomic and molecular physics, with a strong emphasis on molecular breakup via electron or photon interactions. These issues are most relevant not only to the field of molecular dynamics, but also to the understanding of laboratory and astrophysical plasmas. In essence, Prof. Zajfman wishes to determine how, under harsh conditions, molecules are formed in galaxy's diffuse and dense interstellar clouds. Prof. Zajfman’s experiments involve the use of storage rings, advanced devices in which molecular ions move through a circular vacuum at speeds of approximately 10,000 kilometers per second. The “hot” ions that are produced are then cooled to interstellar temperatures by retaining them in the storage ring. In recent years, Prof. Zajfman developed an improved version of the so-called “ion trap” for the study of molecular reactions, thus enabling him to create a tabletop version of the huge and very expensive storage rings. This, coupled with a new technique he developed for long-term ion storage, enables him to reproduce, in the laboratory, some of the conditions (e.g. low temperature and a low-density environment) existing in interstellar space.

Prof. Zajfman also seeks to understand the astrophysical conditions found in star-forming regions or supernova remnants. Stars are born when an interstellar cloud, made up of atoms and molecules, collapses on itself. Prof. Zajfman and his colleagues work to solve the riddle of star formation by recreating interstellar conditions in a laboratory environment. For years, scientists believed that molecular collisions occurring as interstellar clouds collapse cause energy to be released in the form of radiation, which cools the system down. Prof. Zajfman was among those scientists who proved that an important component of this radiating “coolant” was ordinary water.In other studies, Prof. Zajfman has developed new techniques for the direct, three-dimensional imaging of molecular breakup events, providing new insight into these basic chemical processes. In addition to his research, Prof. Zajfman has invested much time and effort in community outreach, to the public in general and youth in particular. One of his goals is to broaden interest in and knowledge of the advances taking place on the scientific front. He has also taught various undergraduate and graduate physics courses, both at the Technion and at the Weizmann Institute

Avishay Gal-Yam Ph.D.

More info

Department of Particle Physics and Astrophysics
Born in Jerusalem, in 1970, Dr. Gal-Yam earned his BSc in physics and mathematics in 1996 and his PhD in physics and astronomy in 2003 at Tel Aviv University. He received NASA’s prestigious Hubble postdoctoral fellowship and spent four years conducting research at the California Institute of Technology. He joined the Weizmann Institute of Science in 2007.
Dr. Avishay Gal-Yam is a cosmic detective who attempts to identify the stars responsible for spectacular stellar explosions called supernovae. Solving these mysteries can provide vital clues for both the origins of the elements that make up the periodic table – including those necessary for life itself – and for cosmological questions about the origin and fate of the universe. For example, Dr. Gal Yam and his team of graduate students and postdoctoral fellows recently announced the discovery of two new types of supernova explosions. One very faint type – that occurs when helium detonates – appears to produce significantly more calcium (vital for life as we know it) and titanium than were thought possible, and probably contributes a significant portion of these critical elements in the cosmos. The second new type of mega explosions is called pair-production supernovae. These are 10 to 100 times more powerful than any previously known type and may be the first supernova explosions to have occurred after the "big bang."
In 2011, Dr. Gal-Yam, received the Krill Prize for Excellence in Scientific Research, and in 2010, the Israeli Physical Society (IPS) Prize for a Young Physicist, the German Federal Ministry of Education and Research ARCHES prize, and Weizmann’s Levinson Physics Prize. His previous honors and awards include a Colton Fellowship (2000), European Union fellowships (1999 and 2007), the Italian Città di Cefalù prize (2006), and the 2008 Peter and Patricia Gruber Award. He has published more than 100 papers in prominent scientific journals, including Nature, Science, and The Astrophysical Journal.
